Something struck the hood with a dull drum-like thud.

"There's another, sir!" cried Kennedy. "There's some one following us!"

"Can you see any one?" came the reply. "I thought I saw something then, about twenty yards behind. It's so dark."

"Try a shot!" I said, passing my Browning to Kennedy.

The next moment, the crack of the little weapon sounded sharply, and I thought I detected a vague, answering cry.

"See anything?" came from Barton.

Neither Kennedy nor I made reply; for we were both looking back down the hill. Momentarily, the moon had peeped from the cloud-banks, and where, three hundreds yards behind, the bordering trees were few, a patch of dim light spread across the muddy road—and melted away as a new blackness gathered.

But, in the brief space, three figures had shown, only for an instant— but long enough for us both to see that they were those of three gaunt men, seemingly clad in scanty garments. What weapons they employed I could not conjecture; but we were pursued by three of Dr. Fu-Manchu's dacoits!

Barton growled something savagely, and ran the car to the left of the road, as the gates of Dr. Hamilton's house came in sight.

A servant was there, ready to throw them open; and Sir Lionel swung around on to the drive, and drove ahead, up the elm avenue to where the light streamed through the open door on to the wet gravel. The house was a blaze of lights, every window visible being illuminated; and Mrs. Hamilton stood in the porch to greet us.
