A young constable in the office came forward as she entered and enquired her business. She disclosed her name, and her relationship with the inmate of Flint House, deeming that would be sufficient to gain her an interview with somebody in authority. In that expectation she was not disappointed. The constable favoured her with a good hard stare, went into another room, and reappeared to say that Inspector Dawfield would see her at once.

She followed him into the inner room, where a slight man of middle age was seated at a leather-covered table opening his morning correspondence. He looked up and bowed as he saw his visitor, but waited until the constable had retired before he spoke.

“Good morning,” he said. “What can I do for you?”

His eye regarded her with a thoughtful glance. His professional interest had been aroused by the strange death of the occupant of Flint House, whose object in visiting Cornwall had been common gossip in the district for some time past.

“It is about my brother’s death that I wished to see you.” Mrs. Pendleton spoke earnestly, drawing her chair closer with the feeling that the man before her had sufficient intelligence to give her a sympathetic hearing.

“So I gathered from your card. It seems a very sad case. Sergeant Pengowan’s report has just reached me. Anything I can do for you—” Inspector Dawfield pretended to occupy himself in cutting open an official envelope with scrupulous care.

“Sergeant Pengowan regards it as a case of suicide, does he not?” asked Mrs. Pendleton rigidly.

“Well, yes, I believe he does,” replied Inspector Dawfield. “There is no doubt on that point, is there? Your brother’s revolver was lying near him, and the door was locked on the inside.”

“There is the greatest doubt in my mind,” returned Mrs. Pendleton vehemently. “I do not—I cannot believe that my brother has taken his own life. In fact, I am sure he did not.”

On hearing these words Inspector Dawfield looked at his visitor again, with something more than surprise in his eyes, then he pulled a document from a pigeonhole and hastily scanned it.
