Case Solved?

Patricia Cornwell may have identified Jack the Ripper. According to a Reuters article she may have done it by matching the Ripper's DNA with that of Walter Sickert, an artist who revelled in painting violent and gruesome killings. Apparently DNA can be identified from the saliva used to lick a postage stamp to post a letter.

Cornwell is the novelist who created Kay Scarpetta, a Virginia crime-solving coroner. I've "read" several of her books, thanks to Books on Tape. She maintains the tension right the way through. Well plotted, too.
