Grey zone

When a student goes missing and a professor ends up dead, Dulcie Schwartz realizes that midterms are going to be worse than ever. She's hard at work on her thesis, but present day concerns, including the destructive mischief of her growing kitten, keep dragging her back into a tangle of motive, misbehavior, and maybe even murder. If only Mr Grey, her beloved feline ghost, would lend a hand, at least with that rambunctious kitten.
