From the Potpourri section of The Misadventures of Ellery Queen anthology edited by Josh Pachter and Dale C. Andrews:

Stephen Coleman is rich, frugal, and able to learn from his mistakes. Like setting up a joint checking account with his wife. A mistake he’s careful not to repeat with wife number two. In “The Last Check” by Patricia McGerr (originally from EQMM March 1972), Coleman leaves a signature on a blank check as his dying message. It could be a clue to his murderer’s identity if only Captain Rogan can sleuth out its meaning.
