Deep Water

The thirty-fourth book in the Cliff Hardy series

Still reeling from the shock death of his partner, Cliff suffers a heart attack-but this isn't enough to keep him from investigating the disappearance of the father of the woman nursing him back to health.
The search for the renowned geologist takes Hardy behind the scenes at one of Sydney's biggest basin aquifers and ignites the wrath of local big businesses which stand to lose even bigger money if his discoveries are revealed.
