Inspector Raglan (The Murder of Roger Ackroyd)

In the novel The Murder of Roger Ackroyd, Inspector Raglan is a Police Inspector from the nearby larger town of Cranchester. He was the chief investigating officer in the initially baffling murder of Roger Ackroyd. He believes the murderer is Roger's stepson, but later he changes idea and accuses Charles Kent as the culprit.

Raglan doesn’t manage to arrest the murderer of Roger, since Hercule Poirot exposed the latter. The killer followed Poirot’s advice and took his own life after writing a manuscript about the crime.
