KILLER RETIREMENTHe's one cranky octogenarian, but Paul Jacobson is all about living for today. Between his hot seventysomething bride, Marion, and a family Christmas vacation in Hawaii, he's never felt better - in spite of his nonexistent short-term memory. So the only reason he's undercover in a Honolulu nursing home is to help police discover who assaulted ailing resident Mrs. Rodriguez. For that he can survive bad food...and fellow patients.But when Mrs. Rodriguez turns up dead and her valuable diamond bracelet goes missing, Paul finds himself neck-deep in sinister shenanigans and secrets nastier than green Jell-O with canned pears. And when someone goes after him and Marion with lethal intent, he'll have to put the pieces together fast to nail the perpetrator - and live to gripe another day.
