"Oh, rather. He loves it."

"Rev. Henry Stutters--Mr. Matthew Cay," read Antony.

"Was that our friend Cayley?"

"Yes."

"Any good?"

"Well, much better than I expected. He wasn't keen, but Mark made him."

"Miss Norris wasn't playing, I see."

"My dear Tony, she's a professional. Of course she wasn't."

Antony laughed again.

"A great success, was it?"

"Oh, rather!"

"I'm a fool, and a damned fool," Antony announced solemnly. "And a
damned fool," he said again under his breath, as he led Bill away from
the poster, and out of the yard into the road. "And a damned fool. Even
now--" He broke off and then asked suddenly, "Did Mark ever have much
trouble with his teeth?"

"He went to his dentist a good deal. But what on earth--"

Antony laughed a third time.

"What luck!" he chuckled. "But how do you know?"

"We go to the same man; Mark recommended him to me. Cartwright, in
Wimpole Street."

"Cartwright in Wimpole Street," repeated Antony thoughtfully. "Yes, I
can remember that. Cartwright in Wimpole Street. Did Cayley go to him

you'd--"

"One last question," he said. "Was Mark fond of swimming?"

"No, he hated it. I don't believe he could swim. Tony, are you mad, or
am I? Or is this a new game?"

Antony squeezed his arm.

"Dear old Bill," he said. "It's a game. What a game! And the answer is
Cartwright in Wimpole Street."

They walked in silence for half a mile or so along the road to Waldheim.
Bill tried two or three times to get his friend to talk, but Antony had
only grunted in reply. He was just going to make another attempt, when
Antony came to a sudden stop and turned to him anxiously.

"I wonder if you'd do something for me," he said, looking at him with
some doubt.

"What sort of thing?"

"Well, it's really dashed important. It's just the one thing I want
now."

Bill was suddenly enthusiastic again.

"I say, have you really found it all out?"

Antony nodded.

"At least, I'm very nearly there, Bill. There's just this one thing I
want now. It means your going back to
