downstairs; and I ascertained; in your presence; Watson; without

cigarette ash; that the prisoner had in our absence come out from
her retreat。 Well; Hopkins; here we are at Charing Cross; and I
congratulate you on having brought your case to a successful
conclusion。 You are going to headquarters; no doubt。 I think;
Watson; you and I will drive together to the Russian Embassy。〃
