Midnight novel of suspense

Spenser earned his degree in the school of hard knocks, so he is ready when a Boston university hires him to recover a rare, stolen manuscript. He is hardly surpised that his only clue is a radical student with four bullets in his chest. The cops are ready to throw the book at the pretty blond coed whose prints are all over the murder weapon but Spenser knows there are no easy answers. He tackles some very heavy homework and knows that if he doesn't finish his assignment soon, he could end up marked "D" -- for dead.From the Paperback edition.
