The private collection of a detective who led the hunt for Jack the Ripper - including notes in which he names a prime suspect - is to go on display for the first time.
Scotland Yard inspector Donald Sutherland Swanson made annotations in a police chief s book about the case.
Known as the Swanson Marginalia, they name Polish-born Aaron Kosminski - since linked to a victim by DNA.
The archive also contains Victorian-era photos, letters and drawings.
In 1888, Jack The Ripper began his reign of terror in the East End of London, murdering and mutilating at least five women.
