"Very unlikely," said Battle.

"But it might happen," persisted Bundle.

"Oh! it might," admitted the Superintendent.

There was a moment or two's silence. Then Bundle said quietly.

"Superintendent Battle, could you give me a list of secret societies that have their headquarters in Seven Dials?"

It was Superintendent Battle's boast that he had never been seen to display emotion. But Bundle could have sworn that just for a moment his eyelids flickered and he looked taken aback. Only for a moment, however. He was his usual wooden self as he said:

"Strictly speaking, Lady Eileen, there's no such place as Seven Dials nowadays."

"No?"

"No. Most of it is pulled down and rebuilt. It was rather a low quarter once, but it's very respectable and high class nowadays. Not at all a romantic spot to poke about in for mysterious secret societies."

"Oh!" said Bundle, rather nonplussed.
