Michael Blumley, Duke of Loriton (age 28),is viewed as an eccentric by his peers in the ton. He does his duty, of course, but his interest—and talent—lies in the science of electricity. He has no interest in what the frivolities of Society. When his favorite aunt, Mary, Lady Harris, leaves her precious, well-behaved black poodle, Lancelot in his care while she travels his life takes an interesting turn.

Elizabeth “Bitsy” Dockering (age 19),third daughter of a viscount, is enjoying her second Season in London. She is a Diamond of the Season and is adored by all—and especially by her precious black poodle, Galahad. To everyone else, however, Galahad is a demon dog. So much so that Peter Cordray, one of Bitsy’s most insistent beaux and a particular victim of Galahad’s bad manners and sharp teeth, has hired a petty thief (Jimmy Bly) to steal the dog, clearing the way for his suit.

When the two dogs and their “people” meet in the park, chaos ensues and unknowingly results in a dog swap. Which means Lancelot is kidnapped instead of Galahad! But when both dogs go missing in an ever thickening dognapping plot, Michael and Elizabeth end up coming together to scour London, recover Lancelot and Galahad all while falling in love.
