William Le Queux,
The Czar's Spy — Chapter 5: Contains Certain Confidences
(1905)
“ Yet surely none but an Italian would use such a weapon, or would aim so truly as to penetrate the heart.And yet the person struck down was a woman, and not a man!A wound from a misericordia always proves fatal, because the shape of the blade cuts the flesh into little flaps which, on withdrawing the knife, close up and prevent the blood from issuing forth. At the same time, however, no power can make them heal again. A blow from such a weapon is as surely fatal as the poisoned poignard of the Borgia or the Medici. ”
