For your true-crime devouring best friend who’s listened to every My Favorite Murder episode:

Rock Paper Scissors By Alice Feeney SEPTEMBER | FLATIRON BOOKS | $27.99

One of the best thrillers of the year so far follows a couple, the cheekily named Mr. and Mrs. Wright, to a desolate Scottish church where they attempt to reignite a dying marriage. But with no one around, can they trust each other? Feeney deftly builds a sinister, eerie mystery, that’ll have readers gasping aloud all the way to a conclusion they’ll never see coming.

The Babysitter: My Summers With a Serial Killer By Liza Rodman and Jennifer Jordan ATRIA BOOKS | MARCH | $28

Part memoir, part true-crime tale, The Babysitter recalls a summer on Cape Cod in the ’60s, where the author’s life intersected with that of little-remembered serial killer Tony Costa, the man who took care of her and her sister while their mother worked.
