When Maria Gibson is shot through the head while standing on the Thor Bridge on her estate, the family's governess, Grace Dunbar, is arrested for murder. Not only does she admit meeting her mistress on the bridge, the police find the murder weapon in her room. She vehemently denies killing the woman and Senator J. Neil Gibson, the dead woman's husband, believes her. He hires Sherlock Holmes to get to the bottom of it all. The Senator admits that he and Miss Dunbar have affections for one another but that neither of them had anything to do with the murder. Dr. Watson is convinced that the Senator is the culprit but Holmes comes to an entirely different conclusion. Written by garykmcd

The Ultimate Revenge
15 February 2014 | by (United States) – See all my reviews

A woman swears revenge against a governess, whom she claims alienated the affections of her children and her husband. Be that as it may, this woman is found murdered on the titled bridge with a bullet in her head. Because a gun of the caliber of murder weapon is found in the governess's drawer, she is arrested for the murder. She finds herself in prison and Holmes and Watson are called in. They must figure out how what appears to be murder may be anything but. The bridge, itself, becomes a bit of a character in the process of unraveling the facts. I really like this story and the methodology as become a bit of a staple for future mysteries. I have to say that when this concluded, I was reminded of the type of mystery that Peter Falk's "Columbo" may have faced.
