Crime fiction where hero/protagonist is in therapy

I'm looking for Crime fiction (Thrillers, mysteries, etc) where the hero or protagonist is in Therapy or seeking therapy. (Not looking for a psychologist/therapist that is the detective.)
Thanks!

Part of Hit Man by Lawrence Block fits the bill.

The Enemy We Know by Glaser, maybe? It looks a bit chic-ficcy, comedy, blackmail, and the heroine is a therapist.

Sherlock Holmes in The Seven Percent Solution. His therapist is Sigmund Freud.

I want to say The Wych Elm, but actually I think the main character wasn't in therapy, he just should have been...

One of the characters in Darling Girls is in therapy, and the sessions are related in away that the reader at first doesn't know which.

The Dept Q series by Jussi Alder-Olsen (it is only tangential so far. I have only read the first two books)
Inspector Bone books by T G Reid. Bone has PTSD. (Also, I can't remember if we "see" therapy or if he just talks about his therapy.)
