From Action No. 49 and No. 50 with 6 black & white pages. "Dredger's got a family motto - fight dirty!" A scientist is taken captive by an Eastern Power and DI6 wants Dredger to volunteer as an exchange. He wants no part, yet is double-crossed by DI6 agents that include Breed. "Dredger finds there's little difference between friends and enemies!" Sold out by DI6, Dredger is now in enemy hands. But will he escape and seek revenge? Heck Yeah, It's Bloody Likely He Will!
Here are the pages I have of it.
