A Puzzle to Be Named Later

From the New York Times bestselling author Parnell Hall comes A Puzzle to be Named Later
"If sweet-looking, gray-haired Miss Marple cursed, smoked, and carried a gun in her purse, she'd be a ringer for Cora Felton."—Booklist
The Puzzle Lady couldn't be happier. Matt Greystone, the rookie sensation who just signed a huge contract with the Yankees after coming to the team as the player to be named later in a trade with the Diamondbacks, winning seventeen games as a starting pitcher, was coming to town to rehab from an arm injury. A diehard Yankee fan, Cora was delighted when Matt invited her to a weekend pool party.
On the plus side, she got to meet Derek Jeter.
On the minus side, she had to solve a puzzle (that was also named later), and a couple of the guests got killed.
Solving murders is right up the Puzzle Lady's alley. Unfortunately, someone has broken into the house of a local psychiatrist and rifled her patient files, and Chief Harper wants Cora to solve that, too.
Cora already knows who broke into the house.
She did!
