The Siamese Twin Mystery

Trapped on a burning mountain, the Queens take refuge with a killer.Dashing detective Ellery Queen and his father are driving over the pothole-scarred Arrow Mountain Road when they come face to face with a wall of flame. They tear back in the other direction, fire at their fenders, and finally find safety in a clearing, at the home of Dr. Xavier, a renowned surgeon. He is a genial man, but his distracted, mysterious smile conceals dark secrets. Passing through one of the drafty hallways, Ellery's father is startled by a pair of eyes burning in the darkness—the eyes of a monster. Could they be trapped on some kind of mountain of Dr. Moreau? Dr. Xavier introduces them to the rest of his household, including his wife, brother, and medical assistant. Everyone's welcoming, but they also seem anxious and cagey. When the good doctor is found shot to death in his study, Queen realizes that he and his father have more to fear than a pair of sinister eyes. The Queens might have escaped the forest fire, but they have leapt into a situation that's every bit as hot.
