You know Penny Coyne. The little old lady who has solved multiple murders in her otherwise sleepy village, despite bumbling local police. A razor-sharp mind in a twinset and tweed. You know Johnny Hawke. Hard-bitten LAPD homicide detective. Always in trouble with his captain, always losing partners, but always battling for the truth, whatever it takes. Against all the odds, against the usual story, their worlds are about to collide. It starts with a dead writer and a mysterious wedding invitation. It will end with a rabbit hole that goes so deep, Johnny and Penny might just come to question not just whodunnit, but whether they want to know the answer.
