About six o'clock
I returned to London by the last train , and on entering my room found a telegram from Ambler making an appointment to call on the following evening . The message was dated from Eastbourne , and was the first I had received from him for some days . Next morning I sat in Sir Bernard 's consulting-room as usual , receiving patients , and the afternoon I spent on the usual hospital round . About six o'clock Ambler arrived , drank a brandy and soda with a reflective air , and then suggested that we might dine together at the Cavour -- a favourite haunt of his . At table I endeavoured to induce him to explain his movements and what he had discovered ; but he was still disinclined to tell me anything . He worked always in secret , and until facts were clear said nothing . It was a peculiarity of his to remain dumb , even to his most intimate friends concerning any inquiries he was making .
