He hardly knew whether he ought to show himself to the doctor or attempt to trail him. But the matter promptly settled itself. Dr. Garshaski saw him. Old King Brady, who was watching him closely, did not fail to note the start he gave. He immediately got up, and the old detective thought it was with the intention of leaving the restaurant, but instead of that he came forward to their table and, putting out both hands, exclaimed: "Mr. Brady! I am rejoiced! My best friend! My savior, I may say! Well, well!" Old King Brady shook hands and invited the doctor to sit down, introducing Leggett as a Secret Service man. "Do you mind if I take my supper at this table?" asked the doctor. "Not at all," was the reply. Having come up with the man, it seemed to the old detective that he might as well listen to anything he had to say. "I thought you were going to China, doctor?" he began. "Did go," replied the doctor. "I have been across twice since I saw you. How is Young King Brady?" "Well." "In San Francisco?" "I don't know where he is just now. He is working for a man on a private matter. It is some little time since I heard from him." "And--I almost hesitate to ask for reasons such as you--you know, Mr. Brady. How is that loveliest of her sex, Miss Montgomery?" Old King Brady's eyes were right upon him as he quietly answered: "I cannot tell you, doctor." "Cannot tell! Has the partnership been dissolved, then?" "Temporarily, yes." "You speak strangely, Mr. Brady. I hope and trust that nothing has gone wrong in that direction. You need not fear to trust me. I have quite recovered from my mad folly, I assure you." "Something has gone very wrong, doctor. It is now several days since Miss Montgomery disappeared right here in San Francisco." The doctor threw up his hands dramatically. "Don't tell me that!" he cried. "Under what circumstances?" "The circumstances belong to Secret Service business. I cannot state them. It may be, however, that she has fallen into the hands of your people." "Now, don't call the Chinese my people. I am the son of a Japanese gentleman, as you well know. You touch me deeply. If there is anything I can do to help, command me." "You are very kind. And your address?" The doctor produced a card. The address it bore was a number on Stockton street. "I have a room in that house just at present," he said. Leggett sat quiet through all this. Still engaging the doctor in conversation, the old detective trod on his toe. The signal was returned. Old King Brady felt that he had been understood, when the Secret Service man suddenly arose and said: "Will you excuse me, Mr. Brady? I have to keep that appointment with Holes." "Go on," said Old King Brady. "You are a bit late for it now." He left himself as soon as the doctor's supper was served. Going around on to China alley, he found Leggett somewhat disguised watching the rear entrance to the house of the Seven Delights.
