KILLER IN THE HOUSE—Kathryn Canavan

A meticulously researched page-turner about one of the Philadelphia suburbs’ most shocking 20th-century crimes. A gunman broke into Jack and Peggy Abt’s house moments after the last family member left for the day. He took a seat next to the upright piano in the living room and waited silently for 11 hours. He didn’t eat. He didn’t sleep. He didn’t watch television. People expect things to go bump in the night, but, in 1976, most adults never fretted a stranger would invade the sanctity of their home in the middle of the day. Six people walked through the kitchen door one by one that afternoon, all expecting nothing more than a Friday night fish fry. The killer leaped out from behind the living room wall over and over and over and over and over and over again. He fired at them at a distance of less than 18 inches, the width of a dining room chair. After each murder, he dragged the body to the basement. Then, to maintain the element of surprise, he sped back upstairs to tidy up for his next unsuspecting victim. This first-person story from a news reporter who was on the scene 90 minutes after the killer slipped away is built from autopsy reports, prison records, IQ tests, trial transcripts, the killer’s own eidetic confession, interviews with witnesses in 1976 and in the 2020s, and the author’s experiences covering the case from the first night to the stunning courtroom moment when the announcement of six death penalties was met with loud cheers. With that research, it was possible to reconstruct the six murders, minute by minute. Tension builds as the six innocent victims turn the kitchen doorknob at 3:30, 4:15, 4:40, 5:15, 6:10 and at 6:30. Readers know their fates, but they didn’t. KILLER IN THE HOUSE: Ten Days of Terror in a Pennsylvania Suburb—Kathryn Canavan
