“It is very difficult to account for,” said Crewe. “Does this dwarf hold spiritualistic séances?”

“Not that I am aware of,” replied the inspector. “If she does, it is in a private capacity, and not as a business.”

“Her acquaintance is worth cultivating. We will go and see her, Marsland.”

Crewe cordially thanked Inspector Murchison for the information he had supplied, and set out with Marsland for Mr. Grange’s shop in Curzon Street.

“A good man, Murchison; he has given us a lot of information,” he said to his companion as they drove along.

“It seemed very scrappy and incomplete to me,” was Marsland’s reply.

“Gossipy is the right word—not scrappy. And there is nothing more valuable than gossipy information; it enables you to fill in so many blanks in your theory—if you have one.”

“You have formed your theory of how this tragedy occurred?” said Marsland interrogatively.

“Part of one,” replied Crewe.

Marsland accepted this reply as an intimation that the detective was not prepared to disclose his theory at that stage.
