'The Man From the Navy' by Alan Fennell

When a boastful Naval Captain arrives in Marineville to demonstrate a new missile, he and Troy immediately experience a clash of personalities. Meanwhile, Surface Agent X20 sabotages the test missile by loading it with real explosives. After Troy narrowly avoids being killed during the test, Commander Shore demands that the naval Captain be court-martialled -unless Troy can swallow his pride and prove the man’s innocence…
