John Brooks

OK, there is this weird phone on my desk at work, that starts to talk to me from time to time. What it sais is always the same "John Brooks, please come to reception"... I'm not John Brooks! Also, there is no John Brooks in my company. Even worse, there is no John Brooks on Strelley Hall grounds!
My interest has been raised, thus I performed some crimminal investigations! NCIS cap on the head, and off we go :-). Sherlock Woods seems to live in Nottingham after all ;-).
Aaaand, my investigations were successful. Turns out, "John Brooks come to reception" is a to secret code! Whenever this password is transmitted, a guy in a van that sells sandwiches has entered Strelley Hall. Btw., his name is NOT John Brooks. The procedure is used to let everyone know that Sandwich-Man is here, while omitting the awkward situation of someone shouting "Sandwichman is here" when companies have customers visiting on site... Frankly, I don't think this is worth the effort, but at least I now know who the famous John Brooks is :-).
