I've located a John Sparrow through a site, explaining associations with companies, but a John Victor Sparrow is very suspicious.

I found something else that gives Mr. John Sparrow's business address as:
John Sparrow
Financial Services Strategy Team
Room 4/18
HM Treasury
1 Horse Guards Road
London SW1A 2HQ
Does he regard himself ONLY as John Victor Sparrow, because I cannot for the life of me think of an instance where a legit firm would impress upon people to know their middle name in all correspondence.
