"The act of speaking, the release from silence, invariably meant that the prisoner would say too much, give something away, let slip an honest truth in the midst of the self-justification. Inspector Singh, like a fine piano-tuner, could listen to these verbal outpourings and pick up those hints of expression or emotion that were off-key and those that rang true. And so he waited for Jasper Lee to open his mouth, and a door to the truth, at the same time."
