watch, and the moment the other emerged from the booking-office and panted towards the labelling rack, Pringle followed on. As Thomas moved off with his machine Pringle palmed a shilling on the porter with the demand, "Same, please," and a few seconds later drew aside to read the label pasted on his spokes. It was Witham. Handing the cycle to a porter he rushed to the booking-office and then on to the platform as the crock, in the indifferent absence of Thomas, was trundled into the van with customary official brutality; his own followed with a shade more consideration, and under the pretence of adjusting it he presently got into the van, and as he passed Thomas's machine buried a knife-blade in each of its tyres. He had just time to take his seat before the whistle sounded, and the train glided out of the station.
Witham was a good forty minutes off, and at every halt Pringle's shoulders blocked the carriage window. He feared lest Thomas should repeat his favourite strategy of alighting before his destination. But so long as they were in motion Pringle whiled the time by imagining fresh reasons for this mysterious journey. He was staring at the map of the Great Eastern system which appositely hung in the compartment, when his eye fell on a miniature steamboat voyaging a mathematically straight line drawn across from Harwich to the Hook of Holland. The figure suggested a new idea. Supposing the present trip had been arranged with an accomplice—could it in brief be a clever scheme to dispose of the diamonds in the best market? What more likely to disarm suspicion than for Thomas to cycle from Witham to Harwich?
"Witham!"
Pringle, with every sense alert, looked out. No one alighting? Yes, here he was. The guard had already evicted the two cycles when Thomas, with the precious valise, hurried down the platform and seized his own. The supreme moment had arrived. Pringle waited until the other had disappeared, and stepped on to the platform as the train began to move. There was no need for him to hurry; the damage he had inflicted on the crock would ensure its leisurely running. And true enough, when he reached the station door Thomas had got but a little way along the road in a bumpy fashion, which even to his inexperience might have told the rapid deflation of the tyres. His progress was further complicated by the presence of the bag, which he had no means of fastening, to the cycle; and, slowly as Pringle followed, the distance between them rapidly shortened, until when Thomas turned into the main road he was nearly up to him. Pringle halted a few seconds to allow a diplomatic gap to intervene, and then followed round the corner as Thomas shaped a painful course along the Colchester road. On and on, growing ever slower, the way led between high edges, until with a pair of absolutely flat tyres there dawned upon Thomas's intelligence a suspicion that all was not well with the machine and, dismounting, he leant it against the hedge.
"Can I lend you a repair? You seem badly punctured," piped Pringle in a high falsetto. He had shot by, and now, wheeling round, passed a little to the rear and propped his machine against a gate.
"I thought that was it. I haven't got a repair," was the least bearish reply that Pringle had yet heard from Thomas.
"You must get both tyres off—like this!" Pringle inverted the crock, and with the dexterity of long practice, ran his fingers round the rims and unnecessarily dragged out both the inner tubes for their entire length. "Catch hold for a second, will you, while I look for a patch."
Thomas innocently laid the bag at his feet and steadied the machine, when a violent thrust sent him diving headlong through the frame. With a spasm of his powerful back muscles he saved a sprawl into the hedge, and was on his feet in another second. Pringle, the bag in hand, was already a dozen yards away. He had noted a fault in the hedge, and for this he made with all imaginable speed. The road sank just here, but scrambling cat-like up the bank, with a rending and tearing of his clothes, his bleeding hands forced a passage through the gap. Once clear of it he doubled back inside the hedge; beyond the gate there stood his cycle, and even as he neared it there was a scream of curses as the thorns waylaid Thomas in the gap. In a bound Pringle was over the gate. The bag was hooked fast upon a staple; desperately he tugged, but the iron held until at a more violent wrench the leather ripped open. He seized the canvas packet within; it crisped in his fingers. Behind there was a furious panting; he could almost feel the hot breaths, but as Thomas clutched the empty bag and collapsed across the gate, Pringle disappeared towards Colchester in a whirl wind of dust.
