Chain of Evidence

Can Detective Joe "Dart" Dartelli uncover the truth? Or, more importantly, does he dare? Detective Joe "Dart" Dartelli made one critical mistake in his police career: He chose to ignore a piece of evidence in a case labeled a suicide that might have been a murder. The dead man was himself a vicious woman-killer who more than deserved his fate, but that ignored evidence pointed to Dart's former mentor, the brilliant forensic specialist Walter Zeller.
Now another suicide victim turns up--the body of a wife-beater--and the evidence clearly shows that the death was self-inflicted .
