"But how," asked Alden, "did Beardsley come to the house without observation? I have found again and again that the thing that is hardest to detect has been done in the simplest and most obvious way. Negative evidence is often no evidence at all; and the thing done most openly more often escapes remark than an attempt at secrecy. In this case two neighbors saw the maids go out on their errand; one saw the dark-faced boy enter. She swore he was an Italian music boy, while in fact he was a mulatto. The servant of a neighbor said she saw the boy leave the house again. They both agreed that he was long and lanky. Everyone else in the neighborhood, with a chance of seeing, testified that no boy came or went. I believe that Beardsley came, as the boy came, in an open way, and was admitted by Miss Hermione. Again, one neighbor swears that she saw the two maids go down the street together; another, that only one went down alone while she was looking. Cross-examined, she could not be sure whether the one maid she saw was the cook, or housemaid, or charwoman, but only that she came out of the Claxton house. The other neighbors had not seen any woman leave the house. This shows what such evidence is worth. I believe Beardsley left the house disguised in the clothes of the boy. The boy was almost grown, Beardsley not large. No doubt, being in the habit of personating spirits and juggling, escape would be no difficulty to him. I am still unable to suggest any motive for the crime." Alden paused. "Go on." The words were spoken breathlessly by Bertha. Alden went on solemnly. "I think, Hermione, you knew the boy's message to be from Beardsley. You must have admitted Beardsley to the house, Hermione! In the night you helped the boy to escape. It is not possible that you did not know that Beardsley had committed the crime. I am convinced that you helped him also to escape. One possible explanation of your action, and the subsequent concealment, is that he extracted some oath of secrecy which you wrongly considered binding." There was a breathless silence. "But I think you have too much good sense to consider such a compulsory promise binding. You have had another reason." There was still silence.
