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.

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.
