Signing On

For some minutes "Joystick" remained silent, enjoying the obvious astonishment of the trio.

"You need not introduce yourselves," he continued. "You are Robert Beverley; you are Jack Villiers, and you are Alec Claverhouse—I presume you pronounce your name in Scots' fashion."

"You are a veritable Sherlock Holmes," declared Villiers.

"I cannot aspire to that degree of intelligence," he remarked. "So, to remove misunderstandings, I will explain. You said you had an appointment at Southampton at three. I mentioned Richborough Chambers, and then you asked if I knew 'Joystick'. Amongst many applications for an interview I had a joint letter signed by you three fellows. I heard Beverley called by name. That accounted for one of you, and left two—Villiers and Claverhouse. One looked like a naval man, the other did not, but he had an accent that hails from north of the Tweed. Simple, eh? and, by the by, since I know your names, there is no reason why I should screen myself under a nom-de-plume or nom-de-guerre, or whatever you like to call it. I'm called Harborough—Hugh Harborough."
