Enhanced descriptions from Syndetics:

It's an old adage that too many cooks spoil the broth. But when a tour of the White House kitchen by a group of foreign chefs ends in murder, it's Olivia Paras who finds herself in the soup...

Due to a government sequester, entertaining at the White House has been severely curtailed. So executive chef Olivia Paras is delighted to hear that plans are still on to welcome a presidential candidate from the country of Saardisca-the first woman to run for office-and four of that nation's top chefs.

But while leading the chefs on a kitchen tour, pastry chef Marcel passes out suddenly-and later claims he was drugged. When one of the visiting chefs collapses and dies, it's clear someone has infiltrated the White House with ill intent. Could it be an anti-Saardiscan zealot? Is the candidate a target? Are the foreign chefs keeping more than their recipes a secret? Once again, Olivia must make sleuthing the special of the day...
