Bill Sikes merely pointed to the empty measure. The Jew, perfectly understanding the hint, retired to fill it: previously exchanging a remarkable look with Fagin, who raised his eyes for an instant, as if in expectation of it, and shook his head in reply; so slightly that the action would have been almost imperceptible to an observant third person. It was lost upon Sikes, who was stooping at the moment to tie the boot-lace which the dog had torn. Possibly, if he had observed the brief interchange of signals, he might have thought that it boded no good to him.
