Together they fight crime!

I have a small to-read list that should keep me entertained until Saturday. It is important to stay entertained. Boredom leads to the internet, and the internet contains spoilers.

Fred Vargas: The Three Evangelists
(original title: "Debout les morts"; I read it in English because I completely thought Fred Vargas was an English man. She's actually a French woman. I suck!)
It's about a trio of historians trying to catch a murderer.

Leonie Swann: Three Bags Full
(original title: "Glennkill"; once more, I assumed the author was British or American. I mean... Swann? I am very proud that I discovered that she is in fact German. That's how I managed to buy the German version and not again get stuck with a translation I wouldn't need!)
It's about a herde of sheep trying to catch a murderer.

When was the last time I read a book about detectives catching murderers?
