It starts out as a fun road trip to Monterey, California, for Zack, Jillian and the two corgis, but when a dead SCUBA diver washes up on the beach where they are walking, well, the group senses a mystery unfolding.

Zack, Jillian, Sherlock and Watson, become embroiled in a race to discover what the diver had been doing, all alone in the bay, when he died. Compounding their investigation is the presence of a group of playful otters, who just so happen to be using what appears to be gold coins as tools to open shellfish. Are the two events related? Could the deceased diver have located a sunken treasure ship off the coast of Monterey?

Readers are loving this cozy mystery series with its two indomitable dog sleuths. Zack, Jillian and the corgis, Sherlock and Watson, are at it again in this delightful series that pulls you right in.
