Someone is imprisoned in a horrible cage! Jack is trying to get caught by Ranger Johnny Wolf! What is Foxie up to? And just who is sharing Jack's basket these days? Things are mixed-up in Doggeroo. Everything was fine until Sarge got sick. Now Auntie Tidge is looking after Jack, but Foxie is being disagreeable (again). When will Sarge be back? In no time, Jack has both a case and a moral dilemma or two. Is it right to leave his most dangerous enemy trussed up in a cage? And, who will mind the pup Preacher while he's off detecting?
