The Golden Dagger: A Bobby Owen Mystery
Interesting whodunnit from the 1950's.A mysterious phone call leads Commander Bobby Owen and the police to an antique dagger covered in blood, but no body.
Lots of potential suspects crop up and it's up to Owen to straighten everything out.
The characters are more well-rounded and less snobbish (with the exception of the upper classes) than those in other mysteries of the same period.
This is the first Bobby Owen book I've tried, but will be getting a few more.
