The Adventure of the Golden Pince-Nez

Holmes. I knew that someone had entered the house cautiously from without. I next examined the corridor. It is lined with coconut matting and had taken no impression of any kind. This brought me into the study itself. It is a scantily furnished room. The main article is a large writing-table with a fixed bureau. This bureau consists of a double column of drawers, with a central small cupboard between them. The drawers were open, the cupboard locked. The drawers, it seems, were always open, and nothing of value was kept in them. There were some papers of importance in the cupboard, but there were no signs that this had been tampered with, and the professor assures me that nothing was missing. It is certain that no robbery has been committed.
