It looks as if someone may have gotten the digital rights to at least the first book in Bill Crider’s Dan Rhodes series, Too Late to Die, although it can’t be Crider himself, since he passed away some years ago. In any case, a new edition, published by Crossroads Press, is free right now in the US and UK. I hate (truly hate) the new cover, which makes Rhodes look like a zombie. But presumably the words are still the same 
, and they were worthy of the Anthony for Best First Novel when originally published in 1987. I read a bunch of the Rhodes books in “dead tree” format back in the 1980s and 1990s and – although my memories are a bit fuzzy – I liked all that I read.

P.S. I got so irritated by the cover that I went and found pictures (sadly, not great quality) of some of the earlier covers. Which are all pretty much better than the new one. You can guess for yourself which one that is…
