Beautiful Sylvia Kaye and another young woman had been seen hitching a ride not long before Sylvia's bludgeoned body was found outside a pub in Woodstock, near Oxford. Morse was sure the other hitchhiker could tell him much of what he needed to know. But his confidence was shaken by the cool inscrutability of the girl he was certain had been Sylvia's companion on that ill-fated September evening. Shrewd as Morse was, he was also distracted by the complex scenarios that the murder set in motion among Sylvia's girlfriends and their Oxford playmates. To grasp the painful truth and act upon it required from Morse the last atom of his professional discipline.
