Oakes belonged to the magnifying-glass school of detection. The first thing he did on entering the room was to make a careful examination of the floor, the walls, the furniture, and the windowsill. He would have hotly denied the assertion that he did this because it looked well, but he would have been hard put to it to advance any other reason.
If he discovered anything, his discoveries were entirely negative, and served only to deepen the mystery of the case. As Mr. Snyder had said, there was no chimney, and nobody could have entered through the locked door.
There remained the window. It was small, and apprehensiveness, perhaps, of the possibility of burglars, had caused the proprietress to make it doubly secure with an iron bar. No human being could have squeezed his way through it.
It was late that night that he wrote and dispatched to headquarters the report which had amused Mr. Snyder.

Two days later Mr. Snyder sat at his desk, staring with wide, unbelieving eyes at a telegram he had just received. It read as follows:
HAVE SOLVED GUNNER MYSTERY. RETURNING…. OAKES.
Mr. Snyder narrowed his eyes and rang the bell. "Send Mr. Oakes to me directly he arrives," he said.
He was pained to find that his chief emotion was one of bitter annoyance. The swift solution of such an apparently insoluble problem would reflect the highest credit on the Agency, and there were picturesque circumstances connected with the case which would make it popular with the newspapers and lead to its being given a great deal of publicity.
Yet, in spite of all this, Mr. Snyder was annoyed. He realized now how large a part the desire to reduce Oakes' self-esteem had played with him. He further realized, looking at the thing honestly, that he had been firmly convinced that the young man would not come within a mile of a reasonable solution of the mystery. He had desired only that his failure would prove a valuable educational experience for him. For he believed that failure at this particular point in his career would make Oakes a more valuable asset to the Agency. But now here Oakes was, within a ridiculously short space of time, returning to the fold, not humble and defeated, but triumphant. Mr. Snyder looked forward with apprehension to the young man's probable demeanor under the intoxicating influence of victory.
