Grey Expectations

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 Esmé 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.
