The Stoneware Monkey, R. Austin Freeman

Some jewels are stolen, and a policeman is killed. Then a doctor is treating a patient who turns out to be suffering from arsenic poisoning. When the patient disappears, the doctor immediately suspects foul play, and findings seem to back that up.

Interesting, though some of the novel seems to be merely a platform for the author to express his disdain for abstract art.

Also, I figured out what was going on fairly quickly.

The Penrose Mystery, R. Austin Freeman

A guy who collects antiques (rather haphazardly) disappears, and a doctor is hired to find out if the collector is alive or dead. The missing man's propensity towards calling things by the wrong names and secretive nature make finding him difficult.

Fairly intriguing, took a bit longer to figure out.

Truly Grim Tales, Priscila Galloway

The author's take on various fairy tales. Some are pretty good.
