arranged between the active thief and his confederates. For this was too big a thing to be entirely the work of one man. Some of the gang must have been waiting along the line in readiness to receive the boxes and carry them to a place of safety. By this time, no doubt, the boxes themselves had been destroyed; but eight thousand pounds in gold takes some moving, and probably a conveyance, a motor for choice, had been employed for this purpose. But nobody appeared to have seen or heard anything suspicious on the night of the murder; no prowling gamekeeper or watcher had noticed anything out of the common. Along the Essex and Norfolk marshes, where the Grand Coast Railway wound along like a steel snake, they had taken their desolate and dreary way. True, the dead body of a man had been found in the fowling nets up in the mouth of the Little Ouse, and nobody seemed to know who he was; but there could be no connection between this unhappy individual and the express criminal. Merrick shook his head as he listened to this from a laborer in a roadside public house where he was making a frugal lunch on bread and cheese. "What do you call fowling nets?" Merrick asked. "Why, what they catches the birds in," the rustic explained. "Thousands and thousands of duck and teel and widgeon they catches at this time of year. There's miles of nets along the road—great big nets like fowl runs. Ye didn't happen to see any on 'em as ye came along in the train?" "Now I come to think of it, yes," Merrick said thoughtfully. "I was rather struck by all that netting. So they catch sea birds that way?" "Catches 'em by the thousand, they does. Birds fly against the netting in the dark and get entangled. Ducks they get by 'ticing 'em into a sort of cage with decoys. There's some of 'em stan's the best part of half a mile long. Covered in over the top like great cages. Ain't bad sport, either." Merrick nodded. He recollected it all clearly now. He recalled the wide, desolate mud flats running right up to the railway embankment for some miles. At high tide the mud flats were under water, and out of these the great mass of network rose both horizontally and perpendicular. And in this tangle the dead body of a man had been found after the storm. There was nothing really significant in the fact that the body had been discovered soon after the murder of Mr. George Skidmore. Still, there might be a connection between the two incidents. Merrick was going to make inquiries; he was after what looked like a million to one chance. But then
