"Can you ask, my dear Watson? Do you imagine that I have no respect for your medical talents? Could I fancy that your astute judgment would pass a dying man who, however weak, had no rise of pulse or temperature? At four yards, I could deceive you. If I failed to do so, who would bring my Smith within my grasp? No, Watson, I would not touch that box. You can just see if you look at it sideways where the sharp spring like a viper's tooth emerges as you open it. I dare say it was by some such device that poor Savage, who stood between this monster and a reversion, was done to death. My correspondence, however, is, as you know, a varied one, and I am somewhat upon my guard against any packages which reach me. It was clear to me, however, that by pretending that he had really succeeded in his design I might surprise a confession. That pretence I have carried out with the thoroughness of the true artist. Thank you, Watson, you must help me on with my coat. When we have finished at the police- station I think that something nutritious at Simpson's would not be out of place."
