"I found Mirpah watering her geraniums in the back garden. She was all impatience to learn the result of my interview. I am thankful that increasing years have not impaired my memory. I repeated to Mirpah every word bearing on the case in point that the Sergeant had confided to me. Then I waited in silence for her opinion. I was anxious to know whether it coincided in any way with my own. I am happy to think that it did coincide. Father and daughter were agreed. "'I think that you have done a very good afternoon's work, papa,' said Mirpah, after a few moments given to silent thought. 'After a lapse of twenty years, it is not likely that Sergeant Nicholas should have a very clear recollection of any conversation that he may have overheard between Captain Chillington and M. Platzoff. Indeed, had he pretended to repeat any such conversation, I should have felt strongly inclined to doubt the truth of his entire narrative. Happily he disclaims any such abnormal powers of memory. He can remember nothing but a chance phrase or two which some secondary circumstance fixed indelibly on his mind. But he can remember a great number of little facts bearing on the relations between his master and the Russian. These facts, considered singly, may seem of little or no importance, but taken in the aggregate, and regarded as so many bits of mosaic work forming part of a complicated whole, they assume an aspect of far greater importance. In any case, they put us on a trail, which may turn out to be the right one or the wrong one, but at present certainly seems to be worth following up. Finally, they all tend to deepen our first suspicion that M. Platzoff was neither more nor less than a political refugee. The next point is to ascertain whether he is still alive.' "Here again the clear logical intellect of Mirpah (so like my own) came to my assistance. Before parting for the night we were agreed as to what our mode of procedure ought to be on the morrow. This most extraordinary case engages all my thoughts. I am afraid that I shall not be able to sleep much to-night.
