The Squire was still in the Fragonard when Swallow got there: from that time he kept a watch.

The Squire remained in the Club for an hour--" "Which proves," interrupted Copplestone, "that he's a member, and that I ought to have followed up my attempt to get in there." "Well, anyway," continued Gilling, "there he was, and thence he eventually emerged, with a kit-bag.

He got into a taxi, and Swallow heard him order its driver to go to King's Cross.

Now Swallow was there alone--and he had just before that met his man scooting round to see if there was a rear exit from the Fragonard, and he hadn't returned.
Swallow, of course, couldn't wait--every minute was precious.

He followed the Squire to King's Cross, and heard him book for Northborough." "Northborough!" exclaimed Copplestone, in surprise.
