On another occasion Aymar had been in quest of a spring of water, when he felt his rod turn sharply in his hand. On digging at the spot, expecting to discover an abundant source, the body of a murdered woman was found in a barrel, with a rope twisted round her neck. The poor creature was recognized as a woman of the neighborhood who had vanished four months before. Aymar went to the house which the victim had inhabited, and presented his rod to each member of the household. It turned upon the husband of the deceased, who at once took to flight. The magistrates of Lyons, at their wits' ends how to discover the perpetrators of the double murder in the wine shop, urged the Procureur du Roi to make experiment of the powers of Jacques Aymar. The fellow was sent for, and he boldly asserted his capacity for detecting criminals, if he were first brought to the spot of the murder, so as to be put _en rapport_ with the murderers. He was at once conducted to the scene of the outrage, with the rod in his hand. This remained stationary as he traversed the cellar, till he reached the spot where the body of the wine seller had lain; then the stick became violently agitated, and the man's pulse rose as though he were in an access of fever. The same motions and symptoms manifested themselves when he reached the place where the second victim had lain. Having thus received his _impression_, Aymar left the cellar, and, guided by his rod, or rather by an internal instinct, he ascended into the shop, and then stepping into the street, he followed from one to another, like a hound upon the scent, the track of the murderers. It conducted him into the court of the archiepiscopal palace, across it, and down to the gate of the Rhone. It was now evening, and the city gates being all closed, the quest of blood was relinquished for the night.
