"I spotted him, of course, from your description, as soon as he got out of the train," replied Gandam. "No mistaking him, naturally--he's an extra good one to watch. He'd no luggage--not even a handbag. I followed him to the taxi-cabs. I was close by when he stepped into one, and I heard what he said. 'Stage door--Adalbert Theatre.' Off he went--I followed in another taxi. I stopped mine and got out, just in time to see him walk up the entry to the stage-door. He went in. It was then half-past eleven; they were beginning to close. I waited and waited until at last they closed the stage-door. I'll take my oath he'd never come out!--never!" Starmidge made a face of intense disgust. "No, of course he hadn't!" he exclaimed. "He'd gone out at the front. I suppose that never struck you? I know that stage-door of the Adalbert--it's up a passage. If you'd stood at the end of that passage, man, you could have kept an eye on the front and stage-door at the same time. But, of course, it never struck you that a man could go in at the back of a place and come out at the front, did it? Well--that's off for the present. And so am I." Vexed and disappointed that Gabriel Chestermarke had not been tracked to wherever he was staying in London, Starmidge went out, hailed a taxi-cab, and was driven down to the city. He did not particularly concern himself about Gabriel's visit to the stage-door of the Adalbert Theatre; it was something, after all, to know he had gone there: if need arose, he might be traced from that theatre, in which, very possibly, he had some financial interest. What Starmidge had desired to ascertain was the banker's London address: he had already learned in Scarnham that Gabriel Chestermarke was constantly in London for days at a time--he must have some permanent address at which he could be found. And Starmidge foresaw that he might wish to find him--perhaps in a hurry. But just then his chief concern was with another banking firm--Vanderkiste's. He walked slowly along Lombard Street until he came to the house--a quiet, sober, eminently respectable-looking old business place, quite unlike the palatial affairs in which the great banking corporations of modern origin carry on their transactions. There was no display of marble and plaster and plate glass and mahogany and heavy plethoric fittings--a modest brass plate affixed to the door was the only sign and announcement that banking business was carried on within. Equally old-fashioned and modest was the interior--and Starmidge was quick to notice that the clerks were all elderly or middle-aged men, solemn and grave as undertakers.
