Maria Gibson

Maria Gibson is the main antagonist of the Sherlock Holmes Story "The Problem at Thor Bridge"

History
The wife of Neil Gibson, the gold king. A very rich American man, who made his fortune in gold. Maria and Neil married when she was young in Brazil, however as she got older and lost her looks, it became clear they had nothing in common Neil began to loose his interest while she remained devoted to him, this led to him treating his wife very badly.

Neil's attentions instead turned to a miss Grace Dumbar, the governess of there children. However while Grace rejected his romantic advances and made that very clear, she was willing to use her influence over him to have him donate large ammounts of his fortunes to charities.

Consumed with envy at her influence and attention over her husband, Maria formulated a plan of revenge, taking a pair of revolvers she discharged a single shot of one and then had it hidden in Miss Grace's wardrobe. Then sent her a message to meet her at Thor bridge. Miss Dumbar in turn sent a message in reply, which Maria kept hold of. Upon Grace arriving she angrily turned on her, and let out her full fury, sending her away. Then using a piece of string tied to a rock, she had the gun go off killing her and pulling the murder weapon into the river. Thus incriminating Grace for her murder.

Worried by these events, Neil Gibson went to Sherlock Holmes with the case. Holmes immediately spotted several problems in Garce killing Marie, and upon investigating, noticed a chip in the stone work where the bullet had ricochet. Realising what must have happened he held a test with Watson's own revolver and proved that it was Miss Gibson who killed herself, to incriminate Miss Dumbar.
