I don't know many French authors of crime books, simply because not many of them are translated in English. So I was very excited when I found a gem like this one. Crossing the Line is actually second in the series and I figured that out by requesting the third one on Netgalley. After the third one, I came back for the previous books. I didn't find the first one, but that didn't stop me from enjoying the next book in the series.
The story begins with anatomy class at medical school when a strange message is found in a tooth of a corp. "I was murdered"-it says. Is it a sick student's joke or is there something more going on? The body belongs to a well-known pharmacist who has committed a suicide. But why would someone who is suicidal leave a message "I was murdered"?
