“When the full story is finally revealed in this disturbing nightmare of a whodunnit, it will well leave readers reeling. A must-read masterpiece.” —Booklist (starred review)    After the death of Inis St. Erme, Dr. Henry Riddle retraces the man’s final moments, searching for the moment of his fatal misstep. Was it when he and his bride-to-be first set out to elope in Vermont? Or did his deadly error occur later—perhaps when they picked up the terrifying sharp-toothed hitchhiker, or when the three stopped at “Dead Bridegroom’s Pond” for a picnic?    As he searches for answers, Riddle discovers a series of bizarre coincidences that leave him questioning his sanity and his innocence. After all, he too walked those wild, deserted roads the night of the murder, stranded and struggling to get home to New York City. The more he reflects, his own memories become increasingly uncertain, arresting him with nightmarish intensity and veering into the irrational territory of pure terror—that is until an utterly satisfying solution emerges from the depths, logical enough to send the reader back through the narrative to see the clues they missed.   An extraordinary whodunnit that is as puzzling as it is terrifying, Joel Townsley Rogers’s The Red Right Hand is a surreal masterpiece that defies classification. It was identified by crime fiction scholar Jack Adrian as “one of the dozen or so finest mystery novels of the 20th century.”  “It is a strange and terrifying story, and the solution of the mystery, while perfectly logical, is not at all what one is led to suspect.” —The New York Times
