Although Adam Scott is a design engineer for Struthers-Ergen, he has strong links with his upbringing on an outback cattle station in the state of Victoria, Australia. When he receives strange letters from his ailing grandfather in a rest home in Melbourne, he decides to combine a visit to him with a survey of irrigation needs in Victoria.

The grandfather dies before he gets to Melbourne, but the mystery of the letters containing crude sketches of a boomerang remain. Adam visits the family’s long-abandoned cattle station and recalls times when, just as the station was about to succumb financially, his grandfather would disappear and return with money to bail it out.

While Adam is in Australia, the firm is slowly losing money through the unexplained loss of contracts. Will there be a link between the last-minute bailing out of the cattle station and recovery of the irrigation manufacturer?

Written in a fast-paced style, this book will appeal to the adventurous.
