Martin Carot

In Un meurtre en sommeil, the French Télévisions film adaptation of Agatha Christie's Sleeping Murder, for the season 1 of the Les Petits Meurtres d'Agatha Christie TV series, Martin Carot is a handwriting expert who assists Larosière and Lampion. Carot is portrayed by Bertrand De Ruyver.

When Lampion discovers a letter which murder victim Séverina Patrominio had written, he notes that the handwriting is different from that on her supposed suicide note. He suggests subjecting their key suspects, Guillaume Parisot, Mr Balmont and his wife to a handwriting test. He suggests asking Martin Carot from Paris to help. Carot examines the handwriting of all three and concludes that they did not write Séverina's suicide note. However, he also concludes that whoever wrote the suicide note is the same person who wrote a letter supposedly sent by Hélène Poliakov from England to say that she was alive and happy.

Carot is listed in the credits as a "graphologue" (graphologist). However, the expertise he deploys in the episode is more akin to forensic handwriting analysis. Graphology is the analysis of the characteristics of handwriting for the purpose of determining the psychological state or personality of the writer--something which is not done here.
