Could a missing book be haunted? Dulcie Schwartz doesn't want to think so, but ever since it disappeared from the university, things have gone from bad to worse - one of her colleagues accused of homicide, and another revealed as an impostor. To top it all off, both the ghost cat Mr Grey and the kitten Esm� seem to have switched their allegiance to her boyfriend. Deprived of feline assistance, Dulcie must uncover the truth by herself, or else find herself on the hook for the theft - and murder.
