Mrs. Jeffries and the Three Wise Women

As the holidays approach, all is merry and bright for Inspector Witherspoon, Mrs. Jeffries, and the staff at Upper Edmonton Gardens...but murder knows no season.
MURDER UPON A MIDNIGHT CLEAR
Christopher Gilhaney isn't a popular man, and he proves why once again when he insults every guest at Abigail Chase's Guy Fawkes Night dinner party. When Gilhaney is shot dead under the cover of the night's fireworks, his murder is deemed a robbery gone wrong. But when the case hasn't been solved six weeks later, Inspector Witherspoon is called upon to find the killer--and quickly!
With Christmas almost here, Inspector Witherspoon and everyone in his household is upset at the possibility of having to cancel their holiday plans--all to solve a case that seems impossible. Only Luty Belle, Ruth, and Mrs. Goodge refuse to give up and let the crime become a cold case. In fact, the American heiress, the charming next-door neighbor, and the formidable cook use all of their persuasive powers to get the others on board, because these three wise women know justice doesn't take time off for Christmas.
