Character
Wealthy man-about-town Doctor (sometimes Sir) Malcolm Muir seems to live a very sedate life in his well appointed penthouse, however unknown to the public at large he is secretly The Grey Mask who, with the assistance of his butler known only as The Dove, makes a specialty to taking down miscreants who pose as supernatural creatures, cults of devil worshipers, old family curses or other supernatural forces, but are really just villains out to steal from the innocent, or in the case of Axis agents, misdirect people while they steal secrets or commit sabotage.
And they would have gotten away with it too if it hadn’t been for that mysterious man in a grey mask and his peg-legged (sometimes two legged) felt cap wearing, African-American or perhaps Asian (it’s hard to tell) side-kick.
