however, when Hunter rushed out with the hound he was
gone, and though he ran all round the buildings he
failed to find any trace of him."

"One moment," I asked. "Did the stable-boy, when he
ran out with the dog, leave the door unlocked behind
him?"

"Excellent, Watson, excellent!" murmured my companion.
"The importance of the point struck me so forcibly
that I sent a special wire to Dartmoor yesterday to
clear the matter up. The boy locked the door before
he left it. The window, I may add, was not large
enough for a man to get through.

"Hunter waited until his fellow-grooms had returned,
when he sent a message to the trainer and told him
what had occurred. Straker was excited at hearing the
account, although he does not seem to have quite
realized its true significance. It left him, however,
vaguely uneasy, and Mrs. Straker, waking at one in the
morning, found that he was dressing. In reply to her
inquiries, he said that he could not sleep on account
of his anxiety about the horses, and that he intended
to walk down to the stables to see that all was well.
She begged him to remain at home, as she could hear
the rain pattering against the window, but in spite of
her entreaties he pulled on his large mackintosh and
left the house.
