Ernie Guelvada is an agent with the British Secret Service.
More specifically, he is an operative working under the direction of renowned spymaster Peter Quayle who, during the Second World War was in charge of a small cadre of highly dedicated and extremely deadly field agents.
Guelvada's employment by Quayle is interesting in that Guelvada is not a British citizen by birth - he would be given citizenship and the freedom to travel wherever he chose in a war-centric and foreigner-wary United Kingdom but he was born a Belgian citizen and only moved to England when things got too hot for him on the Continent due to his run-ins with Nazis. Some refer to him as a Belgian refugee but he proudly corrects them stating he is a "Free Belgian" helping out the Brits.
A fascinating description of Guelvada is given when we first meet him:
"Ernie was disquieting. Definitely disquieting. It was impossible to sit and talk to Ernie, or even to look at him or be in the same room with him, without experiencing a sense of vague discomfort. When you were not with him you wondered about this; concluded that you were suffering from nerves or imagination; that you were stupid. You became certain about the nerves or imagination until the next time you saw Mr. Guelvada, when you noted that the effect of discomfort became greater as you got to know him better.
"Of course you did not get to know him better. No one ever did. Except Kane. Kane knew him, and about the worm that lived in Mr. Guelvada and spent its time wandering from the mind to the guts. When it was in the mind Ernie made people uncomfortable. When it descended to the stomach other-and possibly more interesting-things happened."
In another adventure when Guelvada is instructed to work with a different agent, that man had his own recollection of the Belgian: "Guelvada was as tough as hell, had a peculiar charm-all his own-and no scruples. He'd worked with Kane, stalking and knocking off enemy agents in Lisbon for years. A very bright one-Guelvada-with a hate for anything German that would be hard to beat. The story was that a Panzer Officer had tortured his girl friend in the early days of the war. She died and after that Ernie had only one idea-killing Germans. He actually liked it and took a great pride in his work."
