Propper: The Strange Disappearance of Mary Young

An astounding crime was committed at Woodlawn Amusement Park in Philadelphia. On a hot, busy Sunday in August, a beautiful young girl sat huddled in one of the cars of the ‘Thrills in the Dark’ scenic railway (a type of roller coaster). When the guard tried to collect her fare he saw that she was dead—stabbed through the heart! From the slight clues that were available on the scene, homicide detective Tommy Rankin starts the investigation of this unheard of crime—an investigation that led him in devious ways to the pursuit of an unknown criminal across half the continent and the solution of an amazing mystery.
