The Cloak was the top agent for Britain's Special Squad, nominally a part of Scotland Yard; but he usually operated from his personal headquarters, known as the Secret Sanctum.
Assisted initially by Mole (the tall one with the bald head, big nose and specs) and Shortstuff (the short squirt with the hairy nut and big eyeballs), he then began having adventures in which he found himself also alongside the sexy and flirtatious Lady Shady, the shady lady.
[2] After The Cloak was cancelled, Higgs drew the strip Space School for Whizzer and Chips, and Thundercap for Buster, and contributed to British fanzines.
During the mid-1980s Higgs created Dopey Dinosaur and published a series of 12 rhyming paperbacks aimed at children, in the same format as the Mr Men books by Roger Hargreaves.
Higgs was portrayed, as himself, in Albion #1 (WildStorm, Aug. 2005); the six-issue limited series aimed to revive classic IPC-owned British comics characters — including Higgs' The Cloak — all of whom appeared in comics published by Odhams Press and later IPC Media during the 1960s and early 1970s, such as Smash!, Valiant, and Lion.
