The Siamese Twin Mystery

From the Grand Master Edgar Award–winning author, amateur sleuth Ellery Queen and his father take refuge with a killer in this classic manor-house mystery.

Driving along a lonely mountain road, detective Ellery Queen and his father, Richard, round a bend and nearly run headlong into a forest fire. To escape, they race up the mountain and take shelter at the cliffside manor of Dr. John Xavier, a surgeon of considerable repute. Ellery quickly suspects something strange is going on inside the house—from Xavier’s bizarre references to his work to the pair of eyes Ellery sees burning in the dark—but before he can confront Xavier about what he’s doing in his laboratory, the good doctor is found shot dead while playing solitaire—and the only clue is a ripped six of spades.

With the help of his father, a gruff police inspector, Ellery sets about solving the crime. The suspects include the victim’s valet, a pair of conjoined twins, and the mysterious Mr. Smith. In this game, the stakes are life and death.
