|Night Train to Memphis|
Date: 1994 — used only — Book
Vicki Bliss is suspicious when she's asked to go on an Egyptian cruise to identify a potential thief. But while she is prepared for the thief to be her lover "Sir John Smythe," she isn't prepared for him to show up on the cruise - with his new wife. In a barely contained fury, she misses several clues that could keep her out of danger, because it turns out that in this case, she is not the detective, nor is she the target - she is the hostage in a game she doesn't know exists.
"Sir John" is, as I suspected, featured prominently in another of Peterson's works, a mystery that predates the Vicki Bliss novels. Likewise, I figured out at least one of the characters to be on the side of the bad guys - but I missed others, because much of the cruise can be divided up into camps. (Isn't anyone just along for the ride?) There's even a nod to Peterson's most famous detective, Amelia Peabody, and the fictional tomb she helped to excavate. All in all, it's a very entertaining book.
