Elliott Roosevelt, whose first novel featuring his mother Eleanor as sleuth was "Murder and the First Lady" (1984), didn't offer a shared byline but gave his ghostwriter a nod via a note in his early books, crediting William Harrington as "my mentor in the craft of mystery writing [who] has given me invaluable assistance with the First Lady mysteries." After Elliott Roosevelt died in 1990, his publishers added to his jacket biography for "A First Class Murder" (1991) the claim: "A hard-working and prolific writer, he left behind a number of already-completed Eleanor Roosevelt mysteries."
