Alan Douglas
From Jenny Everywhere Wiki
Alan Douglas was a “British Superspy”. Jenny Over-There thoughtlessly gave away his location to Dyatlov Kruchenkov when Kruchenkov phoned the Multidimensional Finders Service to ask for it, and quickly realised that she “may have messed up” in doing so. (PROSE: The Tribulations of Jenny Over-There)
Behind the scenes
Alan Douglas was the civilian identity of “British Agent 99”, who appeared in Harvey Comics' Pocket Comics in the early 1940s. The character subsequently lapsed into the public domain.
