The smile faded from his ingenuous face the moment the door had closed behind him, and it was a very thoughtful Mr. Carrington who slowly went downstairs and strolled along the pavement. If his morning's interview had puzzled him, his afternoon's interview seemed to have baffled him completely. He even forgot to relapse into the thoughtless young sportsman when he entered the hotel, and his friend the manageress, after eyeing him with great surprise, cried archly:

"A penny for your thoughts, Mr. Carrington! About shooting or fishing, I'm sure!"

Mr. Carrington recovered his pleasant spirits instantly.

"Quite right," said he. "I was thinking about fishing—in very deep waters."

MR. BISSET'S ASSISTANT

At eleven o'clock next morning a motor car drove up to Keldale House and an exceedingly affable and pleasing stranger delivered a note from Mr. Simon Rattar to Mr. James Bisset. Even without an introduction, Mr. Carrington would have been welcome, for though Mr. Bisset's sway over Keldale House was by this time almost despotic, he had begun to find that despotism has its lonely side, and to miss "the gentry." With an introduction, Mr. Carrington quickly discovered that Mr. Bisset and the mansion he supervised were alike entirely at his disposal.

The preliminary discussion on the sporting possibilities of the estate and the probability of its being let next season impressed Mr. Bisset very favourably indeed with his visitor; and then when the conversation had passed very naturally to the late tragedy in the house, he was still further delighted to find that Mr. Carrington not only shared his own detective enthusiasm, but was vastly interested in his views on this particular mystery.
