The Adventure of the Sinister Stranger: An Agatha Christie Short Story. Agatha Christie

      ‘Twice in the course of the last week I have been summoned by telephone to an urgent case – in each case to find that the summons has been a fake. The first time I thought a practical joke had been played upon me, but on my return the second time I found that some of my private papers had been displaced and disarranged, and now I believe that the same thing had happened the first time. I made an exhaustive search and came to the conclusion that my whole desk had been thoroughly ransacked, and the various papers replaced hurriedly.’
