"You think you'll be able to catch him?" inquired Jones, as he picked up his hat.
"He has no suspicion of our visit last night. Our rescue of Lee, although in a measure it proves that Mrs. Darwin had nothing to do with the crime, does not in his opinion help us to locate Cora. He only kept Lee at Hi Ling's to prevent him from giving evidence in Mrs. Darwin's behalf. He will come to the house to-night without the least suspicion that there will be anyone there to greet him as he deserves," and McKelvie laughed.
"Then you know who he is?" I inquired, as Jones left the house.
"I still suspect. I shall not know positively until to-night. And now I'm going to get some sleep. Then we will go over to the Darwin bank. I have a mind to see whether that one hundred and fifty thousand dollars is still there."
Taking advantage of the respite, I went back to my own apartments for luncheon, and returned to Stuyvesant Square in my car. Evidently in McKelvie's mind Cunningham was still under suspicion, yet I could hardly credit that it was Cunningham who had kept the girl a prisoner. He did not resemble Lee.
When we arrived at the bank Mr. Trenton turned us over to Raines, who conducted us to the safe-deposit vault.
"Do you know whether Cunningham was in to-day?" asked McKelvie.
"No, I don't. One of the tellers might be able to tell you," responded Raines.
"Never mind. The strong box will tell me all I want to know," McKelvie answered.
We approached Cunningham's box and Raines inserted his key in the lock. As he pulled it open I leaned closer to look at the interior. Then I gave an exclamation of astonishment. The box was empty! The one hundred and fifty thousand dollars in bills was gone!
