From the Police file on Leclair's murder (October 22nd, 1764):
He was lying on his back on the floor of the vestibule in front of the staircase, with his bare head resting against the door leading to the cellar. He was dressed in ordinary street attire - gray jacket, a vest, two shirts (one heavy and decorated and the other of mousseline), trousers, black woolen stockings, and shoes with copper buckles. His shirts and camisole were stained with blood; he had been stabbed three times by a pointed instrument - above the left nipple, in the lower stomach on the right side, and in the middle of his chest.

No one knows why Leclair, a wealthy man by that stage, left his wife and went to live, apparently alone, in a poor area of Paris. The murderer was never caught. If any film-makers read this: get your act together and make the film. You could even use the "Jean-Marie Leclair" Stradivarius (currently on loan to Guido Rimonda) in the sound track.
