The Northdale Mystery

POW!  An action packed cover that, unfortunately, suffers from that hideous green costume and brown slouch hat.  Many of us may have first been introduced to this particular cover when it was used on the Pyramid paperback reprint of "Mobsmen on the Spot".  Even then I disliked the green suit and cloak.  I have yet to read "The Northdale Mystery" but this review recommends it and that's good 'nuff fer this agent.

Not for nothin' but here is a quick edit of how I would like to see this cover.
