"That is not anything near the value of the horses," said Laird Supsorrow, keeping his eyes fixed upon his cousin so that he might divine where the trap lay.
"No," said Eben, "it is not. But if one of your men rides after—that is, a few hours in the rear, the horses and carriage will be delivered to him at the boundary of the kingdom of Scotland just at the farther side of the Gretna bridge—"
"H-m-m," said Kennedy McClure, "if you deposit the money here, and obtain a written security from his Highness to indemnify me for any damage to the horses or vehicle, you are at liberty to do as you like with Ben Marrick's equipage. On my side I shall arrange with Saunders Grieve, my yardsman, that you shall not be disquieted in taking them."
"Would not a word from my Lord Wargrove suit you?"
"No," thundered the Laird, "let me have his Highness's fist and seal or I shall not let a hoof leave the yard! What is Lord Wargrove to me?"
"Very well, then, cousin. I will send you the document by a sure hand, and I leave the fifty pounds in your hands now, merely taking your receipt for the Duke's satisfaction."
The Spy well knew that there was not the least possibility of getting his Royal Highness to sign such a document, but as he himself was leaving the country for good at any rate, he did not mind adding a little forgery to his other necessary arrangements. Paper and seal were easily accessible in the parlour, where the Duke often kept Eben waiting for hours. He was an expert in other people's penmanship, and the princely scrawl would not present the least difficulty to him. Still, in case of accident, it would be as well to keep back the document till the last possible moment. For his cousin was not a man to be easily hoodwinked, and he might take it into his head to ride over, document in hand, to require the prince acknowledge his own signature.
As he rode away the spy said to himself, "Yes, forgery it is, of course. But sometimes it is worth while tossing a penny to see which it shall be—fortune, or the hangman's rope."
