#3 in Bull Moose Dog Run series featuring chocolate Lab Randolph and his master Harry

Randolph and Harry book on a pet lovers’ cruise following clues that they hope will lead to the whereabouts of the long-lost Imogen, Randolph’s mistress and Harry’s beloved girlfriend.

Although Randolph is far from pessimistic, the ache for Imogen dampens his natural doggy enthusiasm, as exemplified by Chet in Paw and Order. He’s very likable though (“overweight, overly-intelligent”) and this also has a first-rate mystery.
