New series, based in Sydney, from Barry Maitland.

From the Blurb:

Homicide detective Harry Belltree wouldn't usually be looking too hard at an elderly couple's suicide pact. Especially now, when his brother-in-law Greg has just been stabbed to death. But it seems Greg and the old couple had ties to the same man, a bent moneylender with friends in high places - and low.
