BBC made a few of them into mysteries that appeared on PBS 20 years ago or more. They were edgier than a lot of the mysteries they used to play, but I liked them.

I came across a box of many of his mysteries at a garage sale and researched them to sell on eBay. I have a few duplicates here that I kept to read myself. I sold the rest because I know I can get copies at the library. They always have lots of his stuff. :)
