For a time he got no further, and as he sat, gazing vacantly across the moor, the sun went behind a cloud and the freshening wind whistled round the stack.  It got cold and Foster’s pipe burned out, but he did not move.  Hitherto he had been working in the dark, feeling for a clew, but he began to see a glimmer of light and presently clenched his fist with an exclamation.  The light dawned on him in an illuminating flash.

He had been tricked and made a tool.  Carmen had acted by her father’s, or somebody else’s, orders when she gave him the packet, and the man in Edinburgh had enclosed something before he sent him on to Newcastle.  Nobody would suspect him and that was why he had been entrusted with the packet in Canada.  It was now clear that he had been made use of to carry the stolen bonds to Great Britain.  Carmen, of course, knew nothing about them, but had been influenced by Daly.  Perhaps she was in love with him, but in the meantime this did not matter.  Foster filled his pipe again, because he meant to solve the puzzle while the light was clear and his brain was working well.

Alice Featherstone had given him the first hint of the truth when she suggested that the packet was somehow connected with his being watched and Daly’s pursuit of Lawrence.  Of course it was!  The police had not much ground for suspecting him, but he had come to England without any obvious business, and if Hulton or his agents had warned them, they would inquire about strangers from Canada.  Then he began to see why Daly was determined to find Lawrence.

Fred Hulton had been robbed and killed and Daly was implicated in the crime, if he had not committed it himself.  The fellow’s first object was not blackmail; he meant to use his power over Lawrence to ensure his secrecy.  Lawrence was the only person who had seen the murderer.  It could not have been clear if he had mistaken him for the watchman or not when he went into the pay-office at the factory, and as long as a doubt remained Lawrence was the greatest danger the gang had to reckon on.  Foster felt sure there was a gang.  Admitting all this, one could understand why Daly meant to find Lawrence, but Foster began to see how he could make use of the situation.

He had been easily deceived and the plotters no doubt thought him a fool.  Suppose he took advantage of their belief and asked for an answer to his message or something of the kind?  He might by good luck get a letter or find out enough about them to explain what had happened in Canada.  The vague plan appealed to him strongly.  He was savage at the way he had been tricked, and it would be something to circumvent the people who had made him a tool.  Besides, he could not go to the police yet:  Lawrence’s secret must be kept.  He must first of all gain such a hold on Daly as would render him powerless to injure his comrade.  After that, when he knew how far the man was implicated in the robbery, he could decide what ought to be done.  Well, he would go to Newcastle and see Graham, to whom he had given the packet, but he might need help and thought he knew where to find it.  Getting up with a quick, resolute movement, he went back to the house.
