Dead to Rights: "Captain Leopold and the Ghost-Killer" (1974) by Edward D. Hoch

Edward D. Hoch's "Captain Leopold and the Ghost-Killer," originally appeared in the August, 1974, issue of Ellery Queen's Mystery Magazine and reprinted in Leopold's Way (1985), starts out with a routine case for Captain Leopold and Lieutenant Fletcher – a simple case "without a hint of ghosts or impossibilities." Captain Leopold is ready to go home when a fatal shooting is reported on the 15th floor of the Grant Tower.

Martha Aspeth, a cleaning woman working at the Grant Tower, was shot by her estranged husband, Kurt Aspeth ("he wanted younger ones"). Leopold and Fletcher has plenty of eyewitnesses, "five women who work with her," who all saw it happen. Kurt came up to the 15th floor, asked for Martha and "pulled out his gun and started shooting" the moment he laid eyes on her. He then made his exit through the fire escape. So all they basically have to do is send out an alert, wait for him to be picked up and hand the matter over to the prosecutor. A simple, clear cut and uncomplicated case that turns into an impossible crime over night.

Following morning, Fletches has a good news, bad news situation for Leopold. Good news is that they found they found their suspect. Kurt Aspeth had crashed his car into a bridge abutment, on the Expressway near the Grant Tower building, which killed him instantly. However, according to the evidence, the smashup happened about thirty minutes before the shooting where Kurt was "positively identified as the murderer by five witnesses" – who all knew him personally. I liked how Hoch immediately dismissed the obvious, hackneyed explanations. A discrepancy in the records appears out of the question as the accident report is backed up by the medical report. No error due to daylight-saving time or faulty clocks. Kurt's body was identified by his older brother, Felix, who has a passing, brotherly resemblance, but couldn't pass for his twin brother. Fingerprints back up the identification! Felix believes "his brother's spirit killed Martha, after the accident," but Leopold and Fletcher

Leopold and Fletcher are far too grounded and sober minded to take any stock in Felix's claims that "his brother's spirit killed Martha, after the accident," but then what happened during those thirty minutes?

"Captain Leopold and the Ghost-Killer" is one of Hoch's most John Dickson Carr-like impossible crime stories, despite not being a typical impossible crime or traditional locked room mystery. A cross between ghostly phenomenon and bi-location. Hoch brings more than his usual competent craftsmanship to the table in order to explain away this apparent miracle with an inspired solution both imaginative and completely satisfying. There is, perhaps, one coincidence some readers might find a little hard to swallow, but that's that Merrivalean cussedness of all things general for you. However, what I found even more impressive is the overall structure of the story. Hoch took an unfortunate, every day case of spousal murder without a hint of planning or touch of subtlety (i.e. manufactured alibis, locked rooms, etc) and turned it into a Carr-like impossible crime story by introducing an apparent "glitch" in the timeline. It worked. Mike Grost called "Captain Leopold and the Ghost-Killer" a "landmark in such time-centered mysteries" in the Chesterton-Carr tradition and I couldn't agree more. If there's ever going to be a Hoch best-of collection, "Captain Leopold and the Ghost-Killer" deserves to be included.
