Robberies in a small township bring the attention and presence of sub-inspector M'owie from Melbourne to assist SEnior-Constable Parks. An apparently genial Scottish storekeeper and her sons prove to be the thieves - and one a murderer.

P., cleared of a charge of forgery and enabled to marry the captain's pretty niece. (PB)
