Publisher's Summary

This time Mac has gone too far. For Helm to impersonate a Communist courier to whom he bears no resemblance is suicide - and that isn't all. Someone wants to get the layout of the Alaskan Northwest Coastal Defense System, but they aren't the goodies or the baddies. So who the hell are they? And who is the mysterious Holz that Helm is meant to kill?
