The Synopsis:

A necklace belonging to Mrs. Stuyvesant is stolen from Lawyer Smirney's office. It was smuggled in from China years before. Chief Knox is notified and believes Smirney guilty when he finds a diagram in his pocket, and following it, finds a necklace. Ho Fing-Tang, a Chinaman, studying law in the office, is not suspected by Knox, but Spider, a newspaper reporter, believes differently. Ho Fing-Tang is injured and in a delirium keeps repeating "Huns 764." Spider goes to the office and from a book called "Hun's 129 Reports," he extracts the real necklace. The stones Knox found prove to be paste.
