Entombed (Alexandra Cooper #7) by Linda Fairstein

The Silk Stocking Rapist, targeting New York's wealthier women, had made flashy fodder for the press. When he disappeared the police had only a composite sketch of his appearance. Now, four years later, he's back in Assistant DA Alexandra Cooper's territory, where she and detective Mike Chapman have traces of DNA to help them.

But suddenly science is sidelined by history, with the macabre discovery of a woman's body walled up in a historic house. It's the house where Edgar Allen Poe penned an exquisite meditation on passion and revenge - a tale of being buried alive . . . But this corpse, now a skeleton, was nothing to do with Poe. It dates from the late 1970s.

And then the Silk Stocking Rapist strikes again. Or does he? This time the victim is murdered, and he's never killed before. But at least she never realised her greatest fear - of being buried alive. A terror, as Alex discovers, that had its roots in 1978.
