"S'elp me!" exclaimed Melky, "there ain't no other surprises, Zillah? You ain't come round at this time o' night for nothing! What you got to tell, Zillah?--another development?" "Mrs. Goldmark has something to tell," answered Zillah. "We didn't know what to do, and you didn't come, Melky--nobody come--and so we locked the house and thought of Mr. Purdie. Mrs. Goldmark has seen somebody!" "Who?" demanded Melky. "Somebody, now? What somebody?" "The man that came to her restaurant," replied Zillah. "The man who lost the platinum solitaire!" Mrs. Goldmark who had dropped into the chair which Purdie had drawn to the side of the table for her, wagged her head thoughtfully. "This way it was, then," she said, with a dramatic suggestion of personal enjoyment in revealing a new feature of the mystery, "I have a friend who lives in Stanhope Street--Mrs. Isenberg. She sends to me at half-past-ten to tell me she is sick. I go to see her--immediate. I find her very poorly--so! I stop with her till past eleven, doing what I can. Then her sister, she comes--I can do no more--I come away. And I walk through Sussex Square, as my road back to Praed Street and Zillah. But before I am much across Sussex Square, I stop--sudden, like that! For what? Because--I see a man! That man! Him what drops his cuff-link on my table. Oh, yes!" "You're sure it was that man, Mrs. Goldmark?" enquired Melky, anxiously. "You don't make no mistakes, so?" "Do I mistake myself if I say I see you, Mr. Rubinstein?" exclaimed Mrs. Goldmark, solemnly and with emphasis. "No, I don't make no mistakes at all. Is there not gas lamps?--am I not blessed with good eyes? I see him--like as I see you there young gentleman and Zillah. Plain!" "Well--and what was he doing?" asked Purdie, desirous of getting at facts. "Did he come out of a house, or go into one, or--what?" "I tell you," replied Mrs. Goldmark, "everything I tell you--all in good time. It is like this. A taxicab comes up--approaching me. It stops--by the pavement. Two men--they get out. Him first. Then another. They pay the driver--then they walk on a little--just a few steps. They go into a house. The other man--he lets them into that house. With a latch-key. The door opens--shuts. They are inside. Then I go to Zillah and tell her what I see. So!" The three young men exchanged glances, and Purdie turned to the informant. "Mrs. Goldmark," he said, "did you know the man who opened the door?" "Not from another!" replied Mrs. Goldmark. "A stranger to me!" "Do you know Mr. Levendale--by sight?" asked Purdie. "Often, since all this begins, I ask myself that question," said Mrs. Goldmark, "him being, so to speak, a neighbour. No, that I do not, not being able to say he was ever pointed out to me." "Well, you can describe the man who pulled out his latch-key and opened the door, anyhow," remarked Purdie. "You took a good look at him, I suppose!"
