There was some correspondence on this about a year ago on a WW1 forum. http://1914-1918.invisionzone.com/forums/index.php?showtopic=47059&hl

The Times obit of the time confirms his death in hospital at the age of 46, after a short illness. Immediately prior to that he was station commender at Northolt.

He is buried at Podington in Bedfordshire.
