The Inspector And Mrs. Jeffries

Description for THE INSPECTOR AND MRS. JEFFRIES by Emily Brightwell:

IS THERE A DETECTIVE IN THE HOUSE?

She keeps house for Inspector Witherspoon... and keeps him on his toes. Everyone is astonished by the inspector's Scotland Yard successes--but they don't know about his secret weapon. In fact, even he doesn't know about his secret weapon ...because she's as ladylike as she is clever. No matter 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 crime-solver's work is never done...
