Baker Street irregular

the long version

"Baker Street Irregular is a mystery and espionage tale told by a member of a whimsical Sherlock Holmes club born in a speakeasy, as Woody Hazelbaker undergoes America's political struggles in the 1930s and Second World War in the '40s, stretching from the Great Depression's worst year to the beginning of the Cold War. A young New York lawyer, Woody gets a cold dose of reality from a gangster client he keeps secret from the world, then puts stratagems he learned to use when he and other Baker Street Irregulars react to Hitler's war against Europe's democracies" -- from publisher's web site.
