"Mr. Frederick Leighbourne. We have found out that he changed some of the notes, so it is just possibly that he may be accused of the robbery."
"No, no," cried Maria, much agitated, "it cannot be. Mr. Leighbourne did not take that money out of the safe, I can prove it."
"Then do so, and save him from possible arrest."
The girl looked wildly round the room, then she ran to the window, sprang back to open the door and close it again; finally she paused before Frank and seized his hand. The touch thrilled him.
"Mr. Darrel," she said hurriedly, "you are a gentleman, and I will trust you. I have kept silent out of fear of the Blue Mummy Society, but I shall do so no longer. Mr. Leighbourne did not take the money out of the safe, but I can tell you who did."
"Captain Manuel?" asked Darrel with a start.
"No," she said slowly. "Maria Sandoval!"
"You! You!"
"I--I took the money and gave it to Mr. Grent."
