Colonel Anderson

In the novel The A.B.C. Murders, Colonel Anderson is the Chief Constable whose county includes the town of Doncaster. Poirot describes him as "a man of action". When it was learnt that the next murder, under the letter "D" was to take place at Doncaster, Anderson took the fullest measures, including drafting special constables, increasing patrols and stationing plain clothes men to watch the town and race course.

After the murder of George Earlsfield, Anderson took charge of the interview of witnesses.
