The inspector looked puzzled for a moment, then the light of illumination came over his face. He glanced up eagerly; his dark eyes were dancing.

"You don't mean to say that it was Mr. Richford?" he asked.

"Indeed I do," Beatrice said quietly, "I had intended to keep that piece of information to myself, but you have forced my hand. Of actual crime, of actual murder, I am quite sure that Stephen Richford is innocent. But as to the rest I cannot say. At any rate I have concealed nothing that is likely to injure the course of justice."

CHAPTER XIV

Inspector Field took up his hat and gloves from the chair where he had deposited them. He was satisfied, and more than satisfied with the interview. In a short time he had achieved excellent results.

"We will not trouble Mrs. Richford any more at present," he said. "It may be some consolation to her to know that I agree with all her reasonings. But there is plenty of work to do."

Field bowed himself out, followed by Berrington. The latter asked what the inspector was going to do.

"In the first place I am going down to the Yard," Field explained. "I am then going to get rid of my correspondence and have my dinner. After that till it gets dark I propose to pursue what Lord Beaconsfield called a policy of masterly inactivity for a time. Once it is really dark, I intend to go as far as Wandsworth Common, and learn something of the gentleman who is lame and has a private hansom painted black. You see, sir, the scene of the story is changed. The next act must be played out at Wandsworth."

"You have some settled plan in your mind?" Berrington asked.
