He ate a remarkably hearty breakfast and strode off blithely, this time a few minutes ahead of his partner. It was an even more singular thing that Andrew should linger to confer once more with the lady he had so lately regarded as the impersonation of everything suspicious.

Another curious incident happened later in the day. At lunch-time the junior partner left the office, and, without giving an explanation, remained absent through the afternoon. Not that Heriot missed him. He smoked and wrote and rallied Mr. Thomieson, and dictated letters which left his confidential clerk divided between the extremes of admiration for their shrewdness and horror at the terse and lively style in which they were couched; in short, he got through a day's work that sent him home at four o'clock in the best of spirits.

Andrew met him in the hall.

"Hullo," said Heriot, "where have you been all this time?"

"I want to speak to you for a minute," his son replied, and then, as his father turned naturally towards the library door, stayed him. "There's some one in there. Just come into the dining-room for a moment."

"Who's in there?"

Andrew waited till he had got him behind the closed door, and then said very gravely—

"It's Mrs. Dunbar and a friend of hers."

"What friend?—Not old Charlie Munro?"

"A Mr. Brown. Possibly you've not heard of him before, but I understand he's a connection of her late husband's family. She's asked him to come and meet you."
