"No, thanks awfully!" he answered. "I won't really--I must get back--I've such a lot of things to attend to. This is a very beautiful place of yours," he went on, as Harper, whose face had fallen at the visitor's refusal, followed with his sister to where the motor-car waited. "It might be a hundred miles from anywhere." "It's a thousand miles from anywhere!" muttered Harper. "Nothing to do here!" "No hunting, shooting, fishing?" asked Collingwood. "Get tired of 'em? Well, why not make a private golf-links in your park? You'd get a fine sporting course round there." "That's a good notion, Harper," observed Nesta, with some eagerness. "You could have it laid out this winter." Harper suddenly looked at Collingwood. "Going to stop in Barford?" he asked. "Till I settle my grandfather's affairs--yes," answered Collingwood. "Come and see us again," said Harper. "Come for the night--we've got a jolly good billiard table." "Do!" added Nesta heartily. "Since you're so kind, I will, then," replied Collingwood. "But not for a few days." He drove off--to wonder why he had visited Normandale Grange at all. For Mrs. Mallathorpe's explanation of the letter was doubtless the right one: Collingwood, little as he had seen of Antony Bartle, knew what a veritable sleuth-hound the old man was where rare books or engravings were concerned. Yet--why the sudden exclamation on finding that paper? Why the immediate writing of the letter to Mrs. Mallathorpe? Why the setting off to Eldrick & Pascoe's office as soon as the letter was written? It all looked as if the old man had found some document, the contents of which related to the Mallathorpe family, and was anxious to communicate its nature to Mrs. Mallathorpe, and to his own solicitor, as soon as possible. "But that's probably only my fancy," he mused, as he sped back to Barford; "the real explanation is doubtless that suggested by Mrs. Mallathorpe. Something made the old man think of the collection of local books at Normandale Grange--and he immediately wrote off to ask her to see him, with the idea of persuading her to let him have them. That's all there is in it--what a suspicious sort of party I must be getting! And suspicious of whom--and of what? Anyhow, I'm glad I went out there--and I'll certainly go again."
