The Adelphi Theatre is rumoured to be haunted by the ghost of William Terris. Terris was a popular actor who was killed by a jealous rival.
Terris was killed on December 16, 1897 during the run of the "Secret Service". Actor Richard Prince hated Terris and killed him as Terris was unlocking the Adelphi Theatre stage door.
Terris died in the arms of his Mistress, Jessie Milward. As he was dying he whispered "Ill be back".
The first reporting of the ghost at the Adelphi Theatre was 1928. A stranger saw a male figure in Maiden Lane which he said was a ghost. He later identified the figure as Terris from a photograph.
Poltergiest activity started to manifest in the dressing room once used by Milward. In 1956 the ghost of Terris was reported at the Covent Garden Underground.
Later again there was a sighting in the Adelphi Theatre.
