Murder Under the Hammer - Colin Holcombe

Thomas Carter was born in England but has lived in Australia for the last eighteen years.
What is it about a newspaper report of a record price realised at auction for a bronze sculpture in England, that makes him drop everything to return home? and why is he found murdered only a day after arriving?
Are the deaths of an investigative reporter, found shot by an antique gun, and the apparent suicide of an auctioneer, also connected in some way?
These are just some of the questions that Inspector Paul Manley and his team have to find answers to, if they are to solve the mystery.
