4. Heaven’s Gate

The telephone rang in Blackwood's flat at half past two in the morning, a shrill, insistent sound that dragged him from a dream he could not remember but left behind a residue of dread. He fumbled for the receiver in the darkness, his fingers clumsy with sleep.

"Blackwood."

"Inspector, it's Nurse Dunham. From Seaview." Her voice was a whisper, tight with fear. "You said to call if I noticed anything unusual. Something's happening. They've moved up the schedule."

"Moved up what schedule? What are you talking about?"

"The trial. The medication schedule. Dr. Sterling was here tonight. He personally administered doses to five residents. I've never seen him do that before. He's a researcher, not a practicing physician. He doesn't do bedside care."

Blackwood was already out of bed, reaching for his trousers. "Which residents?"

"I don't have the full list. But I know one of them. Agnes Fairchild. The woman you spoke to in the day room."

"Keep them under observation. Don't let anyone give them anything else. I'll be there within the hour."

"Inspector, I could lose my job for this. If anyone finds out I called you—"

"They won't. Just keep those residents safe until I arrive."

He hung up and dialed Lin's number. She answered on the second ring, her voice alert despite the hour. He explained the situation in terse sentences while pulling on his coat.

"I'll meet you there," she said. "And Inspector? Be careful. If Sterling is accelerating the timeline, he knows we're closing in. He may be desperate."

"Desperate men make mistakes. Let's hope he makes one tonight."

The drive to Seaview was a blur of darkness and rain, the road slick and gleaming in the headlights. Blackwood pushed the Rover harder than it had been pushed in years, the engine wheezing in protest. When he arrived, the rest home was dark except for a single light burning in the reception area. Lin's car was already in the car park, and she was waiting for him by the entrance, her collar turned up against the drizzle.

"No one else has arrived or left since I got here," she said. "I checked the visitor log. Sterling signed in at eleven-fifteen and signed out at one-thirty. Two hours. Plenty of time to do whatever he came to do."

They found Nurse Dunham in the staff lounge on the second floor, her face pale and drawn. She was a woman in her forties, with the worn look of someone who had spent too many years caring for people who would never get better. Her hands were shaking as she poured herself a cup of cold tea.

"Tell us everything," Blackwood said.

"I was on the night shift. Dr. Sterling arrived without warning. He said there had been an adjustment to the trial protocol and that certain patients needed to receive their medication on an accelerated schedule. He had the paperwork. It looked official."

"Did he say why the protocol had changed?"

"He said something about data collection. About needing to complete the trial before the end of the quarter. It sounded odd, but he's the principal investigator. I'm just a nurse. I don't have the authority to question him."

"Which patients did he visit?"

Dunham handed him a list written on a scrap of paper. Five names, each with a room number. Agnes Fairchild was third on the list.

"Do you have samples of the medication he administered?"

"He brought the doses with him. In pre-loaded syringes. He said it was a new formulation that needed to be administered directly by the research team. He didn't leave any of it behind."

Blackwood exchanged a glance with Lin. Pre-loaded syringes. A new formulation. Sterling was covering his tracks, ensuring that no evidence remained behind.

"Take us to Mrs. Fairchild," he said.

Agnes Fairchild's room was small and spare, lit only by a nightlight that cast long shadows across the walls. She was awake, sitting up in bed, her eyes wide and unfocused. When Blackwood entered, she turned toward him with the slow, drifting movement of someone moving through deep water.

"You," she said. "The man who asked about the pills."

"Yes, Mrs. Fairchild. I need to know what Dr. Sterling gave you tonight. Do you remember?"

She was silent for a long moment, her lips moving soundlessly. Then: "The blue pill. But different. Stronger. He said it would help me sleep. But I don't want to sleep. Every time I sleep, I dream of falling. And I'm afraid that one day I won't wake up."

"How do you feel now? Any chest pain? Shortness of breath?"

"My heart feels strange. Like a bird beating its wings against a cage." She pressed her hand against her chest. "Flutter-flutter. Flutter-flutter. And then sometimes it stops, just for a moment, and I think, this is it, this is when I go. But then it starts again, and I'm still here."

Lin stepped forward and took her pulse, her fingers pressed against the thin skin of Agnes's wrist. After a moment, she looked up at Blackwood, her expression grim.

"Arrhythmia. Irregular and rapid. We need to get her to a hospital."

"Agreed. Nurse Dunham, call an ambulance. And check on the other four residents. If any of them show similar symptoms, they need to be transported as well."

The next hour passed in a blur of paramedics and flashing lights, the rest home's corridors suddenly filled with the controlled chaos of a medical emergency. Three of the five residents who had received Sterling's injections were showing signs of cardiac distress. The other two appeared stable but were transported as a precaution.

By the time the last ambulance had departed, dawn was beginning to break over the sea, a thin line of grey light on the horizon. Blackwood stood at the entrance to Seaview, watching the sky lighten, his body heavy with exhaustion.

"We have a problem," Lin said, appearing at his elbow. "Nurse Dunham just told me that Sterling took the visitor log with him when he left. The page with his signature, anyway. And the paperwork for the protocol change was on his personal tablet. We have no record of him being here tonight."

"Of course we don't. He's been planning for this." Blackwood rubbed his eyes. "We need those medical records. Blood samples from the five residents. A full toxicology workup. If we can prove that whatever Sterling gave them was designed to cause cardiac arrest, we have our case."

"The hospital will run tests as part of their standard admission protocol. But Sterling's lawyers could argue that any abnormalities were pre-existing conditions. We need a sample from someone who hasn't been dosed yet. A baseline for comparison."

"Then we need to find the remaining trial participants before Sterling gets to them."

They drove to Eastport General Hospital as the sun rose, the grey light gradually warming to a pale gold. Agnes Fairchild had been admitted to the cardiac care unit, where a team of doctors was working to stabilize her erratic heartbeat. Blackwood and Lin were met in the corridor by a young physician with dark circles under her eyes and the harried look of someone who had been on shift for too many hours.

"Inspector. I'm Dr. Chen. I've been treating Mrs. Fairchild. Her condition is unusual."

"Unusual how?"

"She's showing signs of a coagulopathy I've never seen before. Her blood is clotting abnormally, forming microembolisms that are causing transient ischemic events. Essentially, tiny strokes. They're resolving on their own, but the cumulative effect could be catastrophic. We've put her on anticoagulants, but the clotting factors keep spiking. It's as if her body is being instructed to clot."

"Could this be caused by medication?"

"It's possible. We're running a full toxicology panel, but some compounds don't show up on standard screens. We may need to send samples to a specialized lab."

"Send them wherever you need to. And I want the results sent directly to me, not to anyone else. Is that clear?"

Dr. Chen nodded, her expression troubled. "Inspector, if this is being caused by a medication, and if that medication is still being administered to other patients..."

"We're aware of the implications. We're doing everything we can."

They left the hospital and drove back to the station through streets that were beginning to fill with the early morning traffic of commuters and school buses. Blackwood sat in the passenger seat, his eyes closed, his mind working through the pieces of the puzzle.

"Sterling knows we're onto him," he said. "He's trying to tie up loose ends. The five residents last night were the most coherent of the surviving trial participants. The ones most likely to be able to testify about what they were given."

"Agnes Fairchild spoke to us directly. She was a threat. So were the others." Lin pulled into the station car park and killed the engine. "We need protection for the remaining participants. Round-the-clock surveillance."

"Hargreaves will never authorize it. Not without hard evidence."

"Then we need to get hard evidence. Fast."

They spent the morning compiling a report for the Chief Superintendent, documenting everything they had uncovered: the deaths, the crossword message, the toxicology findings, Sterling's late-night visit, the five hospitalizations. Lin typed while Blackwood dictated, his voice flat and methodical, laying out the facts in the precise language of a police report.

When they finished, Blackwood took the report to Hargreaves' office and placed it on his desk. The Chief Superintendent read it in silence, his face growing progressively grimmer with each page.

"This is circumstantial," he said finally. "A crossword puzzle. A financial connection between the coroner and the pharmaceutical company. The testimony of a dementia patient. A late-night visit that isn't documented."

"There are five people in the hospital with identical cardiac symptoms, all of whom received injections from Sterling last night."

"Sterling is a doctor. He was administering medication as part of an approved clinical trial. There's nothing illegal about that."

"The medication was brought in pre-loaded syringes and taken away afterward. There's no record of what was in them."

"Which is not illegal either. It's unusual, but it's not proof of murder." Hargreaves leaned back in his chair. "I'm not saying you're wrong, Hugo. I'm saying you don't have enough. If I take this to the Crown Prosecution Service now, they'll laugh me out of the room. You need something solid. A witness. A document. A confession. Something that can't be dismissed as coincidence or conspiracy theory."

"A witness," Blackwood repeated. "Someone inside Aegis who knows what Sterling is doing and is willing to testify."

"Exactly. Find me that, and I'll give you whatever resources you need."

Blackwood left the office and returned to his desk, where Lin was waiting with a fresh cup of coffee and a stack of printouts.

"I've been going through Aegis employee records," she said. "Looking for anyone who might be disgruntled enough to talk. There's a name that keeps coming up. Dr. Isaac Poole. He was a senior researcher at Aegis until about eighteen months ago, when he left under what HR described as 'acrimonious circumstances.' He filed a wrongful termination lawsuit that was settled out of court. Since then, he's been working as a consultant for a rival pharmaceutical firm in Bristol."

"What was his role at Aegis?"

"He was on the Revivex development team. Specifically, he was responsible for analyzing the compound's metabolic pathways and identifying potential drug interactions."

"Which means he knows exactly how Revivex works. And what its side effects might be." Blackwood took the printouts and scanned them. "Do we have contact information?"

"A mobile number and an email address. I tried calling, but it went to voicemail. I left a message saying we'd like to speak with him about his time at Aegis."

"Keep trying. If he knows something, he may be our best chance."

The afternoon wore on, the station settling into its familiar rhythm of ringing telephones and shuffling paperwork. Blackwood made calls to the hospital, checking on the condition of the five residents. Three were stable; two, including Agnes Fairchild, remained in critical condition. The toxicology results were still pending.

At four o'clock, Lin's persistence paid off. Dr. Poole returned her call, and after a brief conversation, agreed to meet them the following day at his office in Bristol.

"He sounded nervous," Lin said. "Like he's been waiting for someone to ask the right questions."

"Then we need to ask them before someone silences him." Blackwood stood up and reached for his coat. "I'm going back to the hospital. I want to be there when Agnes Fairchild wakes up, if she wakes up. Stay here and keep working on the financial trail. If Aegis has been paying off coroners and settling wrongful death suits, there should be a paper trail somewhere."

The hospital was quiet when Blackwood arrived, the evening shift settling in for the night. Agnes Fairchild had been moved to a private room in the intensive care unit, where monitors beeped and hummed in a steady rhythm. She was asleep, her face pale against the white pillow, her breathing shallow but steady.

Blackwood sat in a plastic chair beside her bed and waited. The hours passed slowly, marked only by the changing of nurses and the distant murmur of the hospital's endless night. He thought of Arthur, alone in his room at Seaview, filling in his final crossword while death crept through his veins. He thought of all the others, the eight whose names he knew and the unknown number whose names he didn't, all of them signed off as natural causes, all of them forgotten.

At some point, he must have dozed off, because he was awakened by a hand on his shoulder. He opened his eyes to find a nurse standing over him, her expression urgent.

"Inspector. Mrs. Fairchild is awake. She's asking for you."

He straightened up and turned to the bed. Agnes's eyes were open, and they were clearer than he had ever seen them. She looked at him with an expression of calm recognition.

"Inspector," she said, her voice a whisper. "I remember now. I remember everything."

"What do you remember, Mrs. Fairchild?"

"The blue pills. They weren't for our minds. They were for our hearts. He told us they would help us think better, but they made our hearts sick. And he knew. He came to see us every week, and he knew. He was waiting for us to die."

"Who? Dr. Sterling?"

She nodded, a single tear sliding down her cheek. "He said we were helping science. He said our sacrifice would save others. But I didn't want to sacrifice. I didn't want to die."

"You're not going to die, Mrs. Fairchild. You're in a hospital. You're safe."

"No." She shook her head weakly. "No one is safe. He has friends everywhere. In the homes, in the hospitals, in the government. He told us so. He said if we ever told anyone, no one would believe us. Because we're old. Because old people die."

Blackwood leaned closer. "Mrs. Fairchild, would you be willing to testify? To tell a court what you just told me?"

She was silent for a long moment. Then she reached out and took his hand, her grip surprisingly strong. "If you can keep me alive until then."

"I will. I promise."

He stayed with her until she fell asleep again, her breathing evening out into the steady rhythm of true rest. Then he stepped into the corridor and called Lin.

"I've got our witness," he said. "Now we need to make sure she stays alive long enough to talk."

"That's not the only problem," Lin said, her voice tight. "I've been monitoring the Aegis financial records. An hour ago, a large sum of money was transferred from one of their corporate accounts to a law firm in London. The same firm that handled the settlement agreements for the families of the deceased trial participants."

"What kind of large sum?"

"Two million pounds. And the payment reference is a case number I don't recognize. I'm trying to trace it, but it's buried under layers of corporate entities."

"Keep digging. I'm coming back to the station."

Blackwood hung up and walked toward the elevator. As he passed the nurses' station, he noticed a man in a dark suit standing by the desk, speaking quietly to one of the nurses. The man turned, and for a moment their eyes met. The man smiled, a cold, professional smile that did not reach his eyes, and walked away down the corridor.

Blackwood watched him go, a chill running down his spine. He had never seen the man before, but he knew, with the certainty of thirty years of police work, that he was not a doctor, not a patient's family member, not a hospital employee.

He was someone sent to watch. And if necessary, to act.

The game was escalating. And Blackwood had the feeling that before it was over, more people would die.
