"But who? who?" he returned.
His sister gave a shrug. "Oh, you'll find out soon enough," she replied, with a smile.
"I shall," he replied, as two men appeared making for the servants' entrance. "Here comes Henry with the locksmith."
Miss Morriston in her stately way looked amused.
"My dear old Dick, you have been making a fuss about it. You will probably find the door open when you go up."
"And I'll know who has been playing this stupid trick," Morriston said wrathfully.
"A footman making love to a housemaid turned the key in a panic at being trapped," Kelson said to his host.
"I dare say," Morriston replied with a laugh of ill-humour. "And he'll have to pay for his impudence."
That explanation by its feasibility was generally accepted as the simple solution of the mystery.
"Come along!" Morriston called. "We'll all go up, and see whether the door is open or not. We shall just be in time to catch the sunset."
