“I am aware of that,” answered the attorney.  “I often remonstrated with Mr. Mainwaring, but to no purpose; for some reason which he never explained he always kept them there.”

“I would never have believed him capable of such recklessness,” said Mr. Thornton.

“Recklessness!” exclaimed Ralph Mainwaring; “it was the biggest piece of imbecility I ever heard of!  What is your opinion now, Mr. Whitney, regarding a robbery in connection with this case?”

“That there has been a robbery I am forced to admit,” the attorney replied, courteously but firmly; “but my opinion of the matter is still unchanged.  I regard the robbery as only incident to the murder.  I do not yet believe it to have led to the deeper crime.”

“Do you know, Mr. Scott, whether any one beside yourself understood the combination of the safe?” Ralph Mainwaring inquired.

“I do not, sir,” the secretary replied, conscious that all eyes had turned upon him at the inquiry and that the detective was observing him closely.

Ralph Mainwaring started.  “The will?  You surely do not think — "

“I think it might be safer in our own possession,” said the attorney, with a peculiar smile.

“And right you are!” added Mr. Thornton, approvingly.  “I wonder you had not thought of that yourself, Mainwaring.”

Meanwhile, Scott, having opened the desk in compliance with the attorney’s request, had looked for the will where he had last seen it on the preceding day, and, failing to find it, was searching through the numerous receptacles containing Mr. Mainwaring’s private papers.  The silence around him became oppressive, and suddenly looking up, he encountered the glance of both Mr. Whitney and the detective, the former with an expression of triumph in his keen eyes.  Perplexed and bewildered, Scott exclaimed in a mechanical tone,-
