from the back of the book:
Monsieur Pamplemousse has been summoned by the director of Le Guide, the prestigious culinary magazine for which Pamplemousse writes restaurant reviews, on a matter of utmost secrecy. The director is in a pickle: his wife's aunt, whose restaurant perpetrates some of the worst food in France, is demanding inclusion in the next issue of Le Guide.
The Hotel du Paradis, home of Aunt Louise's restaurant, is a place of little comfort, and neither Pamplemousse nor his trusty dog Pommes Frites can sleep after their first dinner. But the problem is not merely indigestion. Some items served to Pamplemousse-and slipped under the table to the eager Pommes Frites-contained an aphrodisiac of undeniable potency.
So Pamplemousse must solve not only the director's problem but also the perplexing question of who is spiking this awful food-and why. Along the way he encounters a baguette of bizarre proportions and an all-girl marching band with amour on their minds. Add a soupcon of danger and intrigue-voila!-pure delight!
