The beloved author of a series of children's books is strangled with her typewriter ribbon. Burke determines that the victim meant to leave a clue by pointing to a page in a book of nursery rhymes. But who does the clue lead to: the childrens' TV show hostess, the victim's secretary, the beat poet, the child psychiatrist, or the victim's publisher? When Henry is kidnapped by one of the suspects, the stakes go higher. When Burke finally deciphers the clue, he traps the killer using doctored videotapes recorded by the victim.
