Boney solves the case: Death of a Swagman (Upfield, 1945)

 Arthur Upfield. Death of a Swagman (1945) A swagman dies at a remote shack used to house whoever is sent to check on the wind-driven water pump. An ex-actor who runs a funeral business, and can inhale a cigar’s worth of smoke. An ambitious police sergeant who benefits from Boney’s tutelage. The sergeant’s wise young daughter who captures Boney’s heart. The usual cast of miscellaneous farmers and their hired hands. Boney himself, arrested and imprisoned for a week, during which he paints the fence around the police station an "eye-offending yellow" and learns a lot just by listening. Another nicely done puzzle and several slices of early 20th century Australian outback life. The solution is just barely plausible. Recommended. ***
