When Sunny Coolidge's curmudgeonly boss, Oliver Barnstable, lands in rehab after breaking his leg, Sunny is stuck shuttling between their offices in Kittery Harbor, Maine, and the facility where Ollie is recuperating. And if putting up with temper tantrums from her boss wasn't enough, his rehab roommate, Gardner Scatterwell, is a shameless flirt. But when Scatterwell dies unexpectedly in the night, Ollie is convinced it wasn't from natural causes. He gives Sunny a new assignment: find out who killed the old tomcat. And speaking of cats, Shadow, Sunny's feline partner in crime, takes a peculiar interest in the rehab's resident angel of death: a calico cat called Portia, with an uncanny talent for cozying up to patients right before they pass away. Together, Sunny and Shadow will have to nose out clues to discover if Portia's jinx had anything to do with Gardner's passing or if all his catting around finally got him fixed.
