Noise and dust were all the trace or explanation that he left.

The mazy streets swallowed him; the Hindoo waddled over to the arch and disappeared without a smile on his face to show even interest.

The interrupted trading and bartering went on again, and no one commented or made a move to follow but Joanna.
She watched the fat Hindoo, and made sure that she would recognize him anywhere again.

Then, by a trail that no one would have guessed at and few could have followed, she made her way to Jaimihr's palace--three miles away from Howrah's--where a dozen sulky-looking sepoys lolled, dismounted, by the wooden gate.

There was neither sight nor sound of mounted men, and the gate was shut; but in the middle of the roadway there was smoking dung, and there was a suspicion of overacting about the indifference of the guardians of the entrance.
There was no overacting, though, in what Joanna did.
