"Circumstantial evidence," continued the young man, as if he scarcely heard Lady Audley's interruption--"that wonderful fabric which is built out of straws collected at every point of the compass, and which is yet strong enough to hang a man. Upon what infinitesimal trifles may sometimes hang the whole secret of some wicked mystery, inexplicable heretofore to the wisest upon the earth! A scrap of paper, a shred of some torn garment, the button off a coat, a word dropped incautiously from the overcautious lips of guilt, the fragment of a letter, the shutting or opening of a door, a shadow on a window-blind, the accuracy of a moment tested by one of Benson's watches--a thousand circumstances so slight as to be forgotten by the criminal, but links of iron in the wonderful chain forged by the science of the detective officer; and lo! the gallows is built up; the solemn bell tolls through the dismal gray of the early morning, the drop creaks under the guilty feet, and the penalty of crime is paid."
Faint shadows of green and crimson fell upon my lady's face from the painted escutcheons in the mullioned window by which she sat; but every trace of the natural color of that face had faded out, leaving it a ghastly ashen gray.
Sitting quietly in her chair, her head fallen back upon the amber damask cushions, and her little hands lying powerless in her lap, Lady Audley had fainted away.
"The radius grows narrower day by day," said Robert Audley. "George Talboys never reached Southampton."
