“I agree to the muddle-headed factor,” I rejoined, “and I won’t be unduly ostentatious as to the ganderism. But to return to Thorndyke, it is extraordinarily good of him to allow himself to be burdened with me.”

“With us,” she corrected.

“It is the same thing, sweetheart. Do you know if he is going to give us a long visit?”

“I hope so,” she replied. “Mr. Polton said that he had got through his arrears of work and had this afternoon free.”

“Then,” said I, “perhaps he will give us the elucidation that he promised me some time ago. I am devoured by curiosity as to how he unravelled the web of mystification that the villain, Bendelow, spun round himself.”

“So am I,” said she; “and I believe I can hear his footsteps on the stair.”

“I believe you were going to say ‘baggage,’ ” Marion murmured.
