"No, no. There are one or two finishing touches to be put. But he must arrange about the date of publishing. He will return by the midnight train, but I shall stay in town for the night." Mark locked up the manuscript in a drawer of his writing table, the key of which he carried about him on a chain. And the two men took their departure, leaving Catherine alone.
