The true story of the long-unsolved killing of a celebrity in northern Florida: "A page-turner." — First Coast Living   The murder of Athalia Ponsell Lindsley, a former model and television hostess who was once engaged to Joseph P. Kennedy, Jr., is still notorious more than four decades after it occurred. The only eyewitness said a man attacked Lindsley with a machete in broad daylight on the front steps of her mansion. Gossip swirled that neighbor Frances Bemis knew who killed Lindsley and would notify authorities—and then Bemis was later murdered on her nightly walk.   Police arrested only one suspect for Lindsley's murder, which remains unsolved to this day. Here, Elizabeth Randall replaces the rumors with research, and draws from over one thousand pages of depositions, records, official county documentation, and interviews to reveal the story behind this shocking crime.
