This is the full text of the novel The Further Adventures of Jimmie Dale by Frank L. Packard. In the previous book of adventures, we met Jimmie Dale, a wealthy playboy by day, who at night put on a disguise and became The Gray Seal, a daredevil entering businesses or homes and cracking safes, always leaving a diamond-shaped, gray paper "seal" behind to mark his conquest. This book continues his adventures.
