It was sent from Carter's well-known drug store, and was to the effect that a lady had just sent a boy in from the street to say that a strange crime had been committed in ----'s mansion round the corner. The boy did not know the lady, and was shy about showing the money she had given him, but that he had money was very evident, also, that he was frightened enough for his story to be true. If the police wished to communicate with him, he could be found at Carter's, where he would be detained till an order for his release should be received.
