A CANINE CRUISE. A STORM OF MURDER. A LABRADOR NAMED RANDOLPH: OVERWEIGHT, OVERLY INTELLIGENT-AND OVERBOARD...

For Randolph and his owner, Harry, a struggling artist, it was dog heaven: a pet lovers cruise filled with canine experts and gung-ho trainers-plus plenty of art lectures for Harry and midnight buffets for Randolph.
