Did a down on his luck former student steal a priceless book? Grad student and cat lover Dulcie Schwartz thinks not - and she sets out to prove it

It's spring break, and Dulcie Schwartz has stayed behind in almost-deserted Cambridge, Massachusetts to concentrate on her thesis. But when a former student turned vagrant, Jeremy Mumbles, is found injured, with a valuable missing book clutched in his arms, Dulcie can't seem to let it go. What was he doing with the book? And why has it turned up after all these years?

With Jeremy now the prime suspect for a series of break-ins in the area, Dulcie is determined to clear the unfortunate former scholar's name. But when she finds a connection between the book he was carrying and her own research into an anonymous Gothic author, the search for clues takes on a new intensity - and a new menace.

"I could kill Roland Fenderby"

Dulcie Schwartz has reason to regret those words when she discovers Professor Fenderby's battered body in his office - and finds herself the prime suspect in the ensuing murder investigation.

But someone seems to be deliberately putting her in the frame for his death. Who - and why?

Her academic career in jeopardy, Dulcie must find out the truth - and fast. But when she turns to Mr Grey for advice, he seems strangely silent. Could the spirit of her wise grey cat really be fading from her life for good?
