Cayley told them of what Elsie had heard through the office door that afternoon.

"You were in the library then, of course," said Antony, rather to himself than to the other. "She might have gone through the hall without your hearing."

"Oh, I've no doubt she was there, and heard voices. Perhaps heard those very words. But--" He broke off, and then added impatiently, "It was accidental. I know it was accidental. What's the good of talking as if Mark was a murderer?" Dinner was announced at that moment, and as they went in, he added, "What's the good of talking about it at all, if it comes to that?"

"What, indeed?" said Antony, and to Bill's great disappointment they talked of books and politics during the meal.

Cayley made an excuse for leaving them as soon as their cigars were alight. He had business to attend to, as was natural. Bill would look after his friend. Bill was only too willing. He offered to beat Antony at billiards, to play him at piquet, to show him the garden by moonlight, or indeed to do anything else with him that he required.
