Pipes were got out and cigarettes lighted. For an hour in the hot smoking-room the men sat, talking in undertones and smoking, or dropping off into long silences. Finally the doctor drew out his watch. He sighed as he looked at it.

"Three o'clock, and no sign of Wynne yet. We'll be getting our things on, boys."

Instantly every man rose to his feet. The tension slackened with movement. In comparative silence they stole out into the hall, threw on their coats and hats, and then Tony West nervously slid the bolts of the big front door. It creaked once or twice, but no sound from the still house answered it. West swung it open, and on the whitened step they quietly put on their shoes.

The doctor switched on an electric torch and threw a blob of light upon the gravelled pathway for them to see the descent. Then one by one they went quietly down the steps, and West shut the door behind them.

"Excellent! Excellent!" exclaimed Doctor Bartholomew, as the gate was reached with no untoward happenings. "Not a soul knows we're gone, boys. That's pretty certain. Now, then, out of the gate and turn to the right up that lane. It'll take us to the very edge of the Fens, I believe, and then our search will commence."

He spoke with assurance, and they followed him instinctively. Unconsciously they had made him captain of the expedition. But—no one had heard them, he had said? If he had looked back once when the big gate shut, he might have changed his mind upon that score. With white face pressed close against the glass of the smoking-room window, which looked directly out upon the front path, stood Borkins, watching them as though he were watching a line of ghosts on their nightly prowl.

"Good Gawd!" he ejaculated, as he discerned their dark figures and the light of the doctor's torch. "Every one of 'em gone—every one!" And then, trembling, he went back to bed.

But the doctor did not look back, and so the little party proceeded upon its way in comparative silence until the edge of the Fens was reached. Here, with one accord, they stopped for further instructions. Three torches made the spot upon which they stood like daylight. The doctor bent his eyes downward.

"Now, boys," he said briskly. "Keep your eyes sharp for footprints. Wynne must have struck off here into the Fens, it's the most direct course. He wouldn't have been such a duffer as to walk too far out of his way—if he was bent upon going there at all.... Hello! Here's the squelchy mark of a man's boot, and here's another!"

They followed the track onward, with perfect ease, for the marshy ground was sodden and took every footprint deeply. That some man had crossed this way, and recently, too, was perfectly plain. The footprints wavered a little that was all, showing that the man who made them was uncertain upon his feet. And Wynne had left the house by no means sober!
