Colonel Melrose (The Secret of Chimneys)

In the novel The Secret of Chimneys, Colonel Melrose is the Chief Constable of the county in which the estate of Chimneys and the nearby town of Market Basing is located. If Market Basing is accepted as being located in Berkshire 9from evidence of Dumb Witness), then this would be his county.

There are several chief constables by the name of Colonel Melrose in the works of Christie, spanning several character universes. It is not entirely clear that they are the same person.
