Charles E. P. Murphy
According to the bio on Amazon: "Charles E.P. Murphy is from the UK and determined to write things that other people will, presumably, read. He is very sorry he did that violent thing to the character you liked.
(He is not sorry)
Murphy has currently written and co-written six books - two horror, two spy satires, and two alternate histories - and a number of free stories on his tumblr, http://cepmurphy.tumblr.com."
