From Tatters of the King

Orderly at St Agnes Asylum, present during Dr Bartlett's first interview with Alexander Roby.

Murdered under mysterious circumstances in the laundry room of the asylum on November 5th, 1928. His murder is an apparent copy of the murder of Nurse Cuthbert Yates, nearly a year earlier.

The Tall Man, while intimidating Nathaniel Browne, heavily implied that he had killed Long, but to do so he would have had to travel from Herefordshire to London in no more than an hour, which would appear to be impossible.
