The Diamond Whisperer #926833

1942: With the world at war, a huge shipment of precious diamonds is sent from Europe to Australia to keep them from the clutches of Adolf Hitler and his invading armies, but that cargo goes missing.
Clam, an experienced Australian military intelligence officer, is put in charge of locating and arresting a felon who is rumoured to be involved in diamond trafficking.
At the same time evidence comes to light linking murders previously committed in Australia and five European countries, by an elusive criminal known as The Diamond Whisperer.
It’s up to Clam, his expert investigations team and a volunteer, to hatch a plan that will ensure the interests of Australia, America and Europe are protected.
