From the back:
Mirabella Daws traveled all the way from Australia to Sheridan Square to visit her sister - only to be stabbed to death in the middle of a locked garden. The residents of Sheridan Square all have their own key to the garden, but the more Inspector Whitherspoon and Mrs Jeffries investigate, the more puzzled they become.
To top it off, no one seemed to know Mirabelle was planning to arrive, including her own sister. But someone knew she was coming - someone who wanted to make sure her visit was very short-lived.
She keeps house for Inspector Witherspoon..and keeps him on his toes. Everyone's awed by his Scotland Yard successes - but they don't know about his secret weapon. NO mater how messy the murder or how dirty the deed, Mrs Jeffries' polished detection skills are up to the task...proving that behind every great man there's a woman - and that a crimesolver's work is never done.
