Surgical Suspicion

FBI Agent Sidney Stone is supposed to be celebrating new life—her infant son, her sister’s engagement, a fresh start. But stuck on maternity leave, spiraling through postpartum depression and boredom, the old profiler’s instincts won’t let her rest.

When Sidney’s half-sister Naomi announces she’s marrying John Winkler, a brilliant surgeon with a tragic past, Sidney tries to be happy for them. But tiny details catch her eye: a strange omission in an obituary, an ex-fiancée who died suddenly, a friend’s drunken warning, a flicker of something cold behind John’s careful smile.

As her suspicion grows—fueled by sleep deprivation and not enough answers—Sidney can’t tell if she’s seeing danger or inventing it. Haunted by her own doubts, she risks everything to uncover the truth: is her sister’s fiancé hiding a deadly secret, or is Sidney seeing monsters in the dark where there are none?
