ERIC ALBERT HARRIS - ROYAL ENGINEERS - Research Request please

I have hit a brick wall in researching - Eric Albert Harris, 1881893, Royal Engineers. He is noted in the following link:
https://www.theonlinebookcompany.com...dications/2814
(Thanks Paul (Belly) for pointing this out)
I do not like making assumptions but think this dedication may provide a rough date of death ie 30 December 2008.
I do not have access to 'Ancestry' but believe Eric resided (possibly died) in the Southampton area.
I would much appreciate any advice or findings to assist my further research.
Eric was a keen member of the International Brotherhood of Magicians (IBM) and MAY have had a colourful wartime career. I have written to IBM and await a response.
Any help or advice would be very much appreciated. Particularly if anyone has access to Ancestry or any other similar research site.
On the face of it, his death occurred too soon for me to seek his Service Records, in any case I have not found sufficient clues to chase down the necessary copy death certificate.
Any help very much appreciated - thanks for reading this
Regards
Mike
