“A light!” said Marsland excitedly.

“It is gone now; it was probably a match. There must be some one there. I wonder who it could be?”

“Perhaps it is Gillett. We will soon see.”

“No, we will drive past. It may be some one who wants to escape being seen. We will run the car off the road a little way down past the farm, then extinguish the lights and make our way back.”

He increased the pace of the car so that if there was any one at the farm it would appear that the car was going on to Ashlingsea. They both kept their eyes on the house as the car sped past, but there was no repetition of the flash of light they had seen. Less than half a mile away Crewe shut off the engine, and carefully ran the car off the road on to a grassy path. He extinguished the lights and jumped out of the car. He took an electric torch from his overcoat pocket and after turning it on to see if it was in order he set off in the direction of the farm.

“We will not keep to the road, as there may be some one on the watch,” he said. “Follow me, I know my way across the fields.”

He clambered over the gate of a field and set off at a run, with Marsland following him closely. He led the way over ditches and across hedges and fences until they reached the meadow at the side of the farm. Before climbing the low, brick wall Crewe waited for Marsland.

“You watch the front of the house while I go to the back. If you see any one challenge him in a loud voice so that I can hear you, and I’ll come to your assistance. If I want you I’ll call out.”

They climbed the wall and dropped noiselessly on to the grass. Crewe waited until Marsland had taken up his station behind a plum-tree in the garden, and then crept towards the kitchen door. He stood outside the door listening intently for a few minutes, but as he heard no sound he selected the right key from the bunch he had borrowed from Gillett, and turned the lock. He waited to see if the sound of the turning lock had alarmed any one inside the house. Slowly he turned the handle, opened the door and stepped noiselessly into the kitchen.

A few minutes later Marsland heard him approaching him from the back of the house.
