Amalia, in comments to the previous post, said, I love SF, and I don't think I've ever in my life read a mystery.

The challenge is on to suggest some mysteries Amalia, a devotee of SF, might like.

Loretta suggested: ...perhaps she'd like Sayers' The Nine Tailors, Allingham's The Fear Sign (aka Sweet Danger?) or Stout's The Doorbell Rang? Or perhaps Ellis Peter's Cadfael novels.

Here's my attempt:

The traditional SF problem story and the traditional mystery have a lot in common. So I'm suggesting stories in which the solution logic is tight and the reader has a fair chance to solve the crime.

I therefore recommend the mysteries of Ngaio Marsh, a New Zealand writer, who in my view is the most logically rigorous mystery writer ever. Which is rather odd since she was an actress and stage director, but there you are. Skip the first in the series and read the others in almost any order. I think among her best are A Surfeit of Lampreys and Off With His Head. (US titles may vary.) Marsh wrote from the 1930s to the 1980s and her detective reflects the period.

I've just finished reading A Trace of Smoke by Rebecca Cantrell, set in early Nazi Berlin, and it is brilliant and logically tight. I'm sure it would be SF-reader friendly.

I second Loretta in thinking the Cadfael stories of Ellis Peters might go down well.

I'm assuming everyone's read the Sherlock Holmes stories, but if not, they're mandatory.

Isaac Asimov wrote a series of mysteries: Tales of the Black Widowers. Coming from an SF background they might be an easy introduction.

Does anyone else have suggestions?
