Death Knows No Calendar

This is an excellent locked room mystery by John Bude. An artist is found dead in her studio, apparently murdered by someone but the room was locked from the inside so how did it happen?

As usual, the crime is mostly investigated by an amateur detective (as it is a Golden Age novel), in this case it is Boddy, a former Army officer. He begins to investigate a varied set of suspects, who all possibly had competed for the artist's affections, including a missing priest and the victim's partner.

An interesting murder mystery, though maybe not one for many surprises. The mystery works more for it's ingenuity of how the fairly obvious culprit carried out the crime than anything else but it a perfectly decent story.
