uld you induce Mr. Lexman to lecture
at my house?"

"At Portman Place!" he asked.

She shook her head.

"No, I have a house of my own. A furnished house I have rented at
Blackheath. Will you induce Mr. Lexman to give the lecture there?"

"But why?" he asked.

"Please don't ask questions," she pleaded, "do this for me, Tommy."

He saw she was in earnest.

"I'll write to old Lexman this afternoon," he promised.

John Lexman telephoned his reply.

"I should prefer somewhere out of London," he said, "and since Miss
Bartholomew has some interest in the matter, may I extend my invitation

And so it came about that the name of Belinda Mary Bartholomew was added

The room was a big one and most of the furniture had been cleared out
to admit the guests who had come from the ends of the earth to learn the
story of the twisted candles, and to test John Lexman's theory by their

Scraps of their conversation came to Belinda Mary as she stood in the

used as a study.

"... do you remember, Sir George, the Bolbrook case! I took the man at
Odessa...."

"... the curious thing was that I found no money on the body, only a
small gold charm set with a single emerald, so I knew it was the girl
with the fur bonnet who had..."

"... Pinot got away after putting three bullets into me, but I dragged
myself to the window and shot him dead--it was a real good shot...!"

They rose to meet her and T. X. introduced her to the men. It was at
that moment that John Lexman was announced.

He looked tired, but returned the Commissioner's greeting with a
cheerful mien. He knew all the men present by name, as they knew him. He
