“No; I didn’t hear any sound; which makes me suspect that she did. She would have heard our voices and she is probably keeping a sharp lookout at this very moment. I wonder if she saw you at the window. But whether she did or not, we must go very warily. Neither of us must return to the Temple direct, and we had better separate when we have returned the keys and I will watch you out of sight and see if anyone is following you. What are you going to do?”

“If you don’t want me, I shall run over to Kensington and drop in to lunch at the Hornbys’. I said I would call as soon as I had an hour or so free.”

“Very well. Do so; and keep a lookout in case you are followed. I have to go down to Guildford this afternoon. Under the circumstances, I shall not go back home, but send Polton a telegram and take a train at Vauxhall and change at some small station where I can watch the platform. Be as careful as you can. Remember that what you have to avoid is being followed to any place where you are known, and, above all, revealing your connection with number Five A, King’s Bench Walk.”
