"Was she alone? Or was any one else present?"
"Now I do recall one thing," the apothecary answered. "There was an agent of a wholesale city firm—a travelling agent, yon understand—trying to persuade me into an order on his house. He stepped on one side as she came to the counter, and he perhaps saw her face more distinctly, for he laughed as she left, and said something about a handsome girl putting her lovers out of their misery."
But Mr. Linthicum could remember neither the name of the agent nor that of the firm which he represented. All Philip's questioning elicited no further particulars, and he was obliged to be satisfied with the record of the day and probable hour of the purchase, and with the apothecary's promise of the strictest secrecy.
He rode immediately home, and after a hasty consultation with Madeline, remounted his horse and set out to find Lucy Henderson. He was fortunate enough to meet her on the highway, on her way to call upon a neighbor. Springing from his horse he walked beside her, and announced his discovery at once.
Lucy remembered the day when she had accompanied Julia to Magnolia, during Joseph's absence from home. The time of the day, also, corresponded to that given by the apothecary.
"Did you visit the drug-store?" Philip asked.
"No," she answered, "and I did not know that Julia had. I paid two or three visits to acquaintances, while she did her shopping, as she told me."
"Then try and remember, not only the order of those visits, but the time occupied by each," said Philip. "Write to your friends, and ask them to refresh their memories. It has become an important point, for—the poison was purchased in your name!"
