“No, it was not.”
“By whom?”
“It was slipped into my hand by a man clad in a Mexican costume. I was surprised, of course, but I opened and read it. The man then had disappeared. I wondered how he had identified me, of course, but I supposed that Archie had told him what costume I was wearing. That made me nervous, you see, for I feared he might be ill. I could think of no other reason for his wanting me.”
“When had you previously seen him?”
“Not for half an hour, Mr. Carter, or longer.”
Nick took the note from her again, saying, while he slipped it into his pocket:
“I will keep this for a time, Mrs. Waldmere, if you have no objection.”
“None whatever.”
“Tell me, now, what costume your husband wore.”
“That of a Spanish cavalier.”
