Shellshock

It's the season of peace on earth and goodwill toward men except at R&P Labs, which has been drawn into the middle of a feud between two Seattle seafood restaurants. A customer has died from an unusual form of food poisoning found in oysters and the restaurant where he had his last meal is in trouble. So is R&P, which had just tested their food and given them a clean bill of health. So as Christmas approaches, the R&P team -- Rob, Phil, Ellis, Virginia and Mitch -- find their scientific jobs interrupted by the need for some urgent detective work. In the third book in the series, Mitch goes undercover as a waiter as he and his colleagues join forces with an inept electrician, a Chihuahua and a seagull named Fred to solve the mystery, salvage their reputation and lay some old ghosts to rest.
