Recovering old fingerprints
And in other news...researchers at the University of Technology Sydney have found a way to lift previously unrecoverable fingerprints. Lovely news for crime fighters, not so good for crime writers. I suspect it's getting harder and harder to write a contemporary mystery in which the traditional puzzle predominates. It does however underline one of the basic rules of real crime: if you want to murder someone, it's very important to deny the police a crime scene.
