Deadly Intent - Laraine Stephens

It is October 1923. What looks like a routine report, on the heavy rains battering Melbourne, becomes another case of murder for The Argus's celebrated crime reporter, Reggie da Costa, devotee of fashionable suits and flamboyant automobiles. A flooded basement hides a ghastly secret: the decomposing remains of Cornelius Stout, a wealthy widower, who has been missing for over two years. With an unlikely partner in straitlaced Dotty Wright, Reggie pursues a cold-blooded, manipulative killer with deadly intentions. 

Deadly Intent is the second in the Reggie da Costa Mysteries.
