Tampered a Dr. Zol Szabo medical mystery

Summary: Dr. Zol Szabo chose public health for its noble ideals and predictable hours. He never expected to be intimidated by the Prime Minister's Office, roughed up by the RCMP, or threatened by the Hamilton mob. Though Zol and his team have investigated every centimeter of Camelot Lodge, a residence for healthy seniors blessed with generous pensions and high-ranking political connections, the source of the converted mansion's spate of fatal food poisonings remains elusive. As the death count rises, the outbreak threatens Zol's beloved grandfather Art Greenwood, a military veteran, engineering genius, and piano whiz. The Mounties muscle in, and Zol's boss threatens him with exile. Hamish Wakefield, Zol's friend and colleague obsessed with microbes and car washes, discovers dangers at the Lodge that make the rabid bats in the turret and the dumpster-diving cook seem like minor indiscretions. It takes Art Greenwood, marshaling the insights of his silver-haired companions, to expose the deaths for what they are: a string of murders.--From back cover.
