Crime of Pass-ee-on

Entirely set in an interrogation room, three expats are being investigated for the murder of their friend, Emilie Dubois, after getting caught stealing evidence from a camera store. Someone else has already been arrested for the crime, but Detective Jean-Paul John, aggressively French and a little camp, doesn't buy it. He senses something fishy is going on with these friends – and it's not l'escargot. They all have motives, but which one was enough to push them over the edge... along with Emilie to her death?
