“An exhaustive study of these showed that the guns from which our three bullets were fired had not been taken by the police. That was a discouraging discovery.
“But now, as so often happens, just as we seemed at a standstill, Drew takes a gun from a suspect; he hauls another down from the wall, and behold: here we have the very guns we seek!
“The test bullets fired from the gun of Drew’s suspect are exactly the same as the one fired into Rosy’s body. The ones fired from the gun you took in such a strange manner beside that deserted slip are exactly the same as those fired by the man with the hole in his hand. I will be able to prove this to any jury by the use of enlarged photographs of the bullets. I now have evidence that will convict these two men. Bring me the men!”
“Ah yes!” Drew sighed. “That’s it! Catch the men!”
“But we will do it!” he exclaimed, springing to his feet. “Such men are a menace to any community. No decent, law abiding citizen is safe as long as they are at large. We will get them. We will! We must!”
CHAPTER XXVII
AN ARROW SPEEDS TO ITS MARK
While the old time detective was making these brilliant discoveries, Herman McCarthey and Drew had made little progress in their endeavor to find the men in the case.
They had taken to riding a squad car at night. A special car of great speed was assigned to them. This car was equipped with a loud gong. They worked only on radio squad calls. The moment a call was announced, they threw on the gas. If the case reported was within a certain distance of the place where their car was parked, they set their gong clanging and dashed away.
In this manner, during a two nights’ vigil, they had run down more than twenty squad calls and had learned not one thing to their advantage.
They did not despair. “The fish are here,” was Herman’s sage remark. “We may be obliged to let down the net many times. At last we will get them.”
