“At the drug store,” returned Edith, also in a whisper. “I was about going out when the druggist called me by name. An elderly gentleman, standing near, started and spoke in a low tone to the druggist, asking if I was Nick Carter’s wife.
“Being told that I was, he came to me, handing me his card and this note, with the request that I should give it to you.
“He said that he had intended to call, had even driven past the door, but, on second thought, believed it were not best, and had gone to the drug store, where he was known, and had written the note there.”
“And you came directly back with it?”
“Directly.”
“Where did Mr. Cary go?”
“He got into a cab and drove down Columbus Avenue.”
Nick thought a moment, and said, in a whisper:
“This must have occurred about the time my caller handed in the other card.”
He sprang to his feet and hurried to the parlor.
