A mystery set in a large occupied theater with an unexplained mystery.

In New York City in the early 1930s, a man is poisoned on a crowded streetcar during rush hour. Everyone sees Longstreet die - but no one sees the killer. Inspector Thumm's few clues all lead up a blind alley. He finally seeks the aid of Drury Lane - retired Shakespearean actor, master of disguise, and amateur sleuth. Seated amid the splendor of the vast medieval halls of his castle on the Hudson, Drury Lane hears the story from the inspector.

Presenting an American voice for this legendary Agatha Christie mystery with one of her best denouements.

Trick I - The first thing to vanish is a worthless doorstop. Then, in the twinkling of an eye, goes its rich and elderly owner. And, for the grand finale, both reappear - each as dead as the other. Trick II - From the House of Darkness issues more bafflement. In total darkness and from a distance of 12 feet, four bullets are pumped within an inch of each other into a spectator's back - a feat utterly impossible to perform yet brazenly and undeniably done.

Newlyweds Tricia and Ethan are searching for the house of their dreams. But when they visit the remote manor that once belonged to Dr. Adrienne Hale, a renowned psychiatrist who vanished without a trace four years earlier, a violent winter storm traps them at the estate… with no chance of escape until the blizzard comes to an end. In search of a book to keep her entertained until the snow abates, Tricia happens upon a secret room. One that contains audio transcripts from every single patient Dr. Hale has ever interviewed.
