A Picture of Murder

I always include major spoilers (hidden), to help with my memory  issues. Read them at your peril! 

Much like the others in the series: fun mystery, set in pre WW1 England. Lively widow, Lady Hardcastle, and her maid Florence Armstrong solve another mystery for the police, who are all either bumbling or conveniently unavailable . Plenty of repeat characters, light hearted, good mystery - I guessed part of what was going on, but not all of it. 

A group of film actors are unexpectedly staying with Lady Hardcastle. They have a new film to show and narrate, but several parties are not happy about the plan. Bodies start turning up, and are whisked away by the mortuary van before either the police or Lady Hardcastle have a chance to examine them. Then the mortuary is burnt down.
