Description
A novel where suspense and humor engage in a merciless battle?! Justin is fed up with school. Really fed up. That's why, in the first days of the holidays, he decides to found a detective agency with his two best friends, Odile and Jérôme. The brand-new Mysterium agency will be responsible for solving minor mysteries and investigating minor crimes that don't interest law enforcement. A simple, risk-free plan. That was before the strange Madame Toupette called on their services. And the investigation into the bad jokes played on her obese cat turns out to be much more disturbing than expected.
