This is a question I get asked all the time working in the bookstore: "What would you recommend for somebody who loved "_________"? (fill in the blank)" Usually I can come up with something, but that something can be a bit of a wild guess if it's not a book or genre I normally read. This is where you helpful people come in. If you have a suggestion, I'd love to hear it.
Here's one where I actually have a good idea of what to recommend, but I'm looking for further suggestions. I should note that I don't read mysteries myself. The recommendations I've been making are based off of what I've been told by others. I'd love some recommendations so I can come up with some new books for my Dad, who loves all of the books and authors I've listed here, as well as the accompanying T.V. shows.
Generally, I've found that people who like the Ian Rankin Rebus novels, also like the books by Peter Robinson, P.D. James and Ruth Rendell, and sometimes Elizabeth George. It's usually a safe assumption that they already know about the Morse series. Now, all of those (except the Peter Robinson books) are also either movies or T.V. series, but they're also all set in the U.K.
More recently, given that most people already know about the authors I've listed here, I've started adding recommedations of the books by Henning Mankell and Donna Leon, but when people have already read them too, then I'm out of suggestions. What other authors are there who write in a similar style or setting?
