Harvard professor Wilson Chaney's position in life is hanging by a thread; his marriage, his reputation, not to mention his tenure at Harvard are in the hands of a blackmailer, someone threatening to sell Chaney's secrets at very high prices. His enviable life could disappear into thin air should the blackmailer's evidence-proof of his affair with a young student-become public knowledge.

So he hires Boston private investigator Carlotta Carlyle to track down the blackmailer and put a stop to the scheme. Can she do it? Of course, but should she? The professor doesn't inspire much loyalty-after all, he did commit adultery with one of his own students-but Carlotta agrees. Digging into the case, nosing around Harvard and the possible suspects from the rest of Dr. Chaney's life, she uncovers a suspicious death as part of the backstory to Dr. Chaney's situation. Suddenly Carlotta's sixth sense is telling her the case might be more complicated-and more dangerous-than it first seemed.
