An Eye for an Eye by William le Queux

The startling statement of Morris Lowry caused me very considerable uneasiness. On my return to Grey's Inn, however, I made no mention of our strange conversation to Dick, who returned that evening rather late after a heavy day of news-hunting. Old Lowry had evidently been in a confidential mood that afternoon, and I had no right to expose any secret of his extraordinary business. Therefore I kept my own counsel, pondering deeply over his statement when Cleugh had gone forth to meet Lily, wondering whether it might have been some other woman who had worn the brooch with the five of diamonds.

I sat at the window gloomily watching the light fade from the leaden London sky. The evening was stifling, for no fresh air penetrated to that small open space, surrounded as it was by miles and miles of smoke-blackened streets, and as night crept on the heavens became a dull red with the reflection of the myriad lights of the city.
