Love crime novels. Love the middle-aged, morose, driven crime novel detective. Here are just a few of my favourites in this category: Morse, Lewis, Bosch, Wallander, Rebus, Perez, DCI Banks,  Frost,  Foyle,  Cannon,  Montalbano,  Harry  Hole,  Jesse  Stone,  George  Gently, Longmire.

Readers keep sending more names. Add Vera (fits the bill despite being female) and Jack Irish.
