The music had ceased , and the night air was not too cold . Not a soul was in sight out on the starlit parade . Not an unusual sound was heard . There was nothing to indicate the faintest trouble ; and yet Captain Buxton , the commanding officer , had been called out by his `` striker '' or soldier-servant before eleven o'clock , had not returned at all , and in little over half an hour had sent for the officer of the day . What did it mean ? Questioning and talking thus among themselves , somebody said , `` Hark ! '' and held up a warning hand .
