Cozy Mysteries discussion

For those who have read this series, how is it? More than the quality of the books I'm interested in knowing if it contains sex, profanity, excessive violence or gruesome details. I'm looking for something fun and clean, like a Poirot or a Sherlock Holmes book. To sum it up, is this series cozy?

I have not read it, but looks like it is a historical fiction, definitely not a cozy.

Ok maybe i misinterpreted what the definition of cozy mystery is (i didn't know a cozy mystery cannot be historical for exemple), but what most I am interested to know is if it is clean or not.

There are historical cozies, but this doesn’t sound like a cozy mystery. It sounds more mainstream. Amazon describes it as a thriller. I recommend reading the following discussion:

Also, looks like you can preview the book on Amazon:

I read all of them and I don't think they are cozy at all. Some are quite dark.
