Books 7, 8, and 9 of the Cassie Pengear Mysteries series in one volume.

The Death Downstairs
When Cassie Pengear’s landlady asks her to check the references of the new tenant downstairs, she expects it to be a simple matter of confirming what was provided. She did not expect it to lead to a dead body in the flat below hers, a series of thefts in the building, and mysterious events at a bank she’s done typing for. If Cassie wants to feel safe in her flat again, she’ll have to solve the death downstairs.

Mugs, Murder, and Mayfair
Cassie Pengear was expecting a quiet week helping her friends Kate and Ada inventory their Mayfair tinkering/haberdashery shop, with nothing more exciting to worry about than a shaving mug thrown through the window, hiding the evidence of a student prank they assume. But then a body is found a few streets away, and the inspector in charge of the murder case begins to suspect Kate. Now Cassie must help her friend by finding the connections between mugs, murder, and Mayfair.

Murder Near Slaughter
Cassie Pengear was expecting a relaxing holiday in a Cotswolds village near Lower Slaughter, staying in a cottage borrowed from a friend of her landlady. She was not expecting to spend most of her first day there trying to find someone to give them the key to the cottage. And she definitely wasn't expecting to walk in the front door and find a dead body on the sitting room rug. Now the local police consider her and Mrs. Albright suspects, and the London man she was counting on to clear them turns out to be Inspector Wainwright. If she wants to clear their names, Cassie will have to solve the murder near Slaughter.

In a Victorian England that almost existed, a steampunk London where tinkerers and clockwork devices exist alongside hansom cabs and corsets, murder is still solved by traditional observation and intuition. This is the London where American typist Cassandra Pengear finds herself stumbling over corpses and helping Scotland Yard detectives solve murders (although they inexplicably prefer to call it interfering). Follow her adventures in the Cassie Pengear Mystery series, beginning with The Killing at the Carnival.
