“We have not had sufficient time to investigate the whole of the facts connected with Mrs. Courtenay’s mysterious death,” the inspector went on. “You will probably recollect, sir, a mystery down at Kew some little time ago. It was fully reported in the papers, and created considerable sensation—an old gentleman was murdered under remarkable circumstances. Well, sir, the gentleman in question was Mrs. Courtenay’s husband.”

The coroner sat back in his chair and stared at the officer who had spoken, while in the court a great sensation was caused. Mention of the Kew Mystery brought its details vividly back to the minds of everyone. Yes. After all, the death of that poor costermonger, Lanky Lane, was of greater public interest than the representatives of the Press anticipated.

“Are you quite certain of this?” the coroner queried.

“Yes, sir. I am here by the direction of the Chief Inspector of Scotland Yard to give evidence. I was engaged upon the case at Kew, and have also made inquiries into the mystery at Neneford.”

“Then you have suspicion that the deceased was—well, a person of bad character?”

“We have.”

“Fools!” growled Ambler. “Lane was a policeman’s ‘nose,’ and often obtained payment from Scotland Yard for information regarding the doings of a certain gang of thieves. And yet they actually declare him to be a bad character. Preposterous!”

“Do you apply for an adjournment?”

“No, sir. We anticipate that the verdict will be suicide—the only one possible in face of the evidence.”

And then, as though the jury were compelled to act upon the inspector’s suggestion, they returned a simple verdict. “That the deceased committed suicide by poisoning while of unsound mind.”
