She took the letters from the postman and went indoors. One of the letters was for herself. It was addressed to her in her name before she married, the name she had neither signed nor seen written for five years. It puzzled her that the writer of the letter should be familiar with her present address and yet be ignorant of her change of name. She could not recall having seen the handwriting before. The postmark was London. It was doubtless due to the mistake in the name on the envelope that the letter had not found its way into Arnott's box at the post office, and so have been collected by him when he fetched his own letters on the previous evening. She went into the sitting-room, and seated herself near the window, and turned the envelope about in her hands. Flailing to identify her correspondent from the superscription, she finally opened it, and withdrawing the closely written sheet of foreign paper, glanced first at the signature. "Lucy Arnott" was written in clear, firm characters at the foot of the page. Pamela's amazement was unbounded. Who was Lucy Arnott? And why should a connection of her husband address her as Miss Horton? She concluded that it must be a connection of her husband; it was such an unlikely accident that a stranger of the same name would write to her. Curious, and vaguely troubled, Pamela began to read. She read the letter through, read with white, set face, and a mind which failed to grasp the significance of what the cold, formal phrases expressed with perfect lucidity. It occurred to her that the thing was a cruel hoax, a wicked, malicious lie. She could not credit the truth of the writer's assertion that she was Herbert Arnott's lawful wife, and that therefore Pamela was not a wife at all--was not legally married... Pamela tried to realise this abomination, and then thrust the horror from her as too terrible for credence. It could not be. She knew that she was married. She had her marriage certificate. Everything had been done in order. Whoever Lucy Arnott was, she could not disprove that.
