I'm looking for a crime and detective novel I read a long time ago.

Title: Crime novel – detective’s wife in coma, beach murder, attraction to colleague

Hey everyone,

I’m searching for a crime/detective novel I read ages ago and can’t recall the title. Here’s everything I remember:

The main character is a male detective.

His wife is in a vegetative state after an accident.

He’s pursuing a serial killer targeting women.

The first victim is discovered on a beach by a jogger.

As the investigation unfolds, the detective struggles with attraction to a female colleague.

The tone is serious/emotional, with his wife’s condition playing a big role in his internal struggle.

I likely read it in the early 2000s (maybe late ’90s), and it could be American or British.

Does anyone recognize it? Any clues would be a huge help — I’ve been searching for years.
