While Guard members Saxon, Kenzie and Lieam were tracking the path of the grain merchant, Gwendolyn has sent word to another of the Guard, Sadie. Sadie, who once watched the shoreline region of the Mouse Territories, is to make contact with another missing mouse, Guard member Conrad, as there have been no outgoing communications from his Northern shoreline dwelling "Calogero".
Sadie arrives at Calogero to find it abandoned, or so it appears. She is quickly met by the peg-legged Conrad, who relates that the grain merchant from issue #1 is a traitor who would meet his mysterious master, who always remained in the shadows at Calogero. The duo plan to leave for Lockhaven at first light to warn them, but are surrounded during the evening by crabs. Conrad sacrifices himself to the crabs so that Sadie may have a chance to escape and warn the Mouse Guard of the traitor.
