The Answerth family's mansion seems to deserve its nickname of Venom House - perhaps because of its forbidding setting, an island in the centre of a man-made lake, its treacherous waters studded by the skeletons of long-dead trees. Perhaps it's because of the unquiet ghosts of the Aboriginals slaughtered by the Answerth ancestors. Whatever the reason, most people are content to give Venom House and its occupants a wide berth... until a couple of corpses turn up in the lake...
The strength of Upfield's accomplishment in this book is so overwhelming it makes the reader cower. The characters are well-developed, the conversation vernacular for the Australian outback, and the development compelling. The story is the nearest Upfield comes to a story that would have made Edgar Allen Poe envious, Upfield maintains a kind of corpse-like humour which is very amusing... The whole book is first-class Upfield and first-class crime fiction. - from The Spirit of Australia by Ray Brown.
