Inspired by the Robert Louis Stevenson classic, this new Wishbone adventure finds our hero following the trail of a strange and evil man in 19th-century London. Joe Talbot's neighbor, Wanda Gilmore, meets the man of her dreams. But Joe, Ellen Talbot, and Wishbone are puzzled by the change in Wanda's personality -- she's just not herself. Wanda invites the Talbots to attend her mystery man's amateur-talent-night show, and everyone is in for a hair-raising surprise! This intrigue reminds Wishbone of the book Strange Case of Dr. Jekyll and Mr. Hyde, by Robert Louis Stevenson. Wishbone imagines himself as John Utterson, a lawyer who follows the trail of a strange and evil man who is terrorizing nineteenth-century London. As Utterson unravels this mystery, he will face dark secrets, witness a frightening scientific experiment gone wrong, and have a fur-raising encounter with a monster!
