Thaddeus Willforce Van Leyden
Van Leyden runs a small antique business on Walnut Street in the French Hill District, Arkham. The odd thing with Mr Van Leyden is that he is business doesn't seem to attract that many customers - still he appears to be quite well off. Clearly Van Leyden has some other income from an unknown source. The local rumours has it that Van Leyden is in league with the O'Bannion mob and thus he is antique store must be some kind of front for the renowned Mobster.
