Brian Leno offers another auto in the rogue’s gallery of Jack the Ripper:
Charles Warren is not really a serious suspect for The Ripper, but in Stephen Knight’s very interesting Jack the Ripper: The Final Solution is presented as being an instigator in keeping the killer’s identity secret, for political reasons.
He was Metropolitan Police Commissioner during the Whitechapel murders and was obviously inept in his fruitless search for Jack.
He resigned on November 9, 1888, the day Mary Jane Kelly’s body was found. I doubt anybody was sorry to see him go. A good man, perhaps, but nabbing The Ripper was beyond his capabilities.
