"I really have not much definite information," said the barrister. "Thus far I am building chiefly on surmise, but I have undoubtedly come into contact with the persons who organized and planned, if they did not actually carry out, the raid on the Albert Gate mansion." "Then you have news of Jack?" broke in Fairholme excitedly. "Not exactly. All I can do at present is to assure you that the scent is hot, and we may run our quarry to earth some few minutes after eleven o'clock to-morrow morning." "I am jolly glad that there is a chance of my being useful in this matter," said the earl gleefully. "If only I am a little bit instrumental in recovering her brother, Edith hasn't got a leg to stand on in the matter of getting married. That's awkwardly put, isn't it? What I mean is that when Talbot is restored to his family and everything is satisfactorily cleared up, Edith and I can get spliced immediately, can't we?" "I regard it as the most assured fact we have yet encountered," said Brett, pleasantly. "But you haven't told me yet the exact manner in which I can be useful." "No," said the barrister. "I have been revolving in my mind the possibilities of to-morrow morning, and you must play an important part in what, by chance, may turn out to be a melodrama. Now, listen to me carefully. In the neighbourhood of the Porte St. Martin there is a street known as the Rue Barbette. At eleven o'clock to-morrow I go to the house No. 11 in that street, and you will accompany me as far as the door. It will be your duty to stand outside and take note of all persons who enter or leave the house once I have disappeared from view in the interior. You must exercise your powers of observation most minutely, paying heed to the height, build, complexion, and clothing of any individual, male or female, who enters or leaves No. 11, Rue Barbette, after you have taken your stand in the street. It is more than probable that no person will demand scrutiny, unless it be some chance tradesman's assistant visiting the building in pursuance of his ordinary work. However, do you feel capable of attending to this part of the programme?" "Perfectly." "You will maintain watch until 11.30. If at that hour I have not rejoined you, make your way to the nearest policeman, and tell him that you have good reason to believe that a friend of yours has either been murdered or suffered serious personal injury in a room on the second storey of the house in question. You will then, in company with the policeman, come rapidly to the apartment I have indicated and demand an immediate entrance--if necessary bursting the door open." "And what then?" gasped the amazed earl. "I really don't know," said Brett imperturbably. "It is possible you may find my gory corpse in one of the inner rooms. The best I can hope for is that I shall be simply a prisoner, but I fully expect to be seriously injured at the very least."
