GLASS ALIBI

Prologue: 8:47 PM

The Meridian Gallery — 40th Floor. Manhattan. March 14th.

Conrad Vane died in front of two hundred people, and not one of them saw it happen.

This was not because they were inattentive. The guests at the Meridian Gallery's twenty-fifth anniversary gala were the most observant people in Manhattan's art world — curators, critics, collectors, journalists. People who made their living looking. Who could spot a forged brushstroke at six feet, a fraudulent provenance in a sentence. They were, collectively, the most perceptive room of people Conrad Vane had ever assembled, and he had assembled them deliberately, because Conrad Vane had always preferred to be seen clearly.

He had stepped onto the terrace at 8:43 PM. Several people noticed — Conrad was not a man who moved through a room without drawing attention. The glass walls of the Meridian's top floor meant the terrace was visible from every angle inside: from the main gallery, from the bar, from the private reception alcove. Every camera in the venue had a sightline to the terrace. The night was cold but clear, the city below doing its perpetual luminous thing.

He stood at the railing for four minutes. He had a glass of champagne. He looked at the city.

At 8:47 PM he pressed his right hand to his chest, the gesture of a man feeling something wrong. The champagne glass left his hand. He turned toward the glass doors — back toward the warmth and the light and the two hundred people who could see him through the walls.

He did not make it to the doors.

He was on the terrace floor by 8:48.

The first person through the doors was his assistant, Owen Fitch, who had been watching through the glass and had seen Conrad turn. Three guests followed. A cardiologist in the crowd took over from the paralyzed caterer who had reached Conrad first. The cardiologist worked for eleven minutes.

At 8:59 PM, she sat back on her heels and looked at the others and said nothing, because nothing was what there was to say.

Within the hour, the NYPD had the guest list, the footage from nine cameras, and the statements of forty-seven witnesses who had been watching the terrace at the moment Conrad Vane collapsed.

Every camera showed the same thing: Conrad Vane, alone on the terrace, dying.

Every witness said the same thing: no one went near him.

The medical examiner, three days later, would write cardiac arrest in the cause-of-death field and mean it — the heart had stopped, this was factual — and it was the correct answer to the wrong question.

The right question was: why had it stopped?

That question belonged to Detective Priya Saul, who received the case on a Monday morning not because it was classified a homicide — it wasn't, not yet — but because a twenty-nine-year-old woman named Nadia Vane had walked into the Twentieth Precinct and said, with the specific quiet conviction of someone who had been preparing this sentence for three days: "My father was murdered. I need someone who will not dismiss this because the word cardiac appears on a document."

The desk sergeant had sent her to Priya.

Priya, as it happened, had been looking for the right question too.
