“The next point that impressed me was the manner of Mrs. Wilson’s death. She died of cancer. Now people do not die suddenly and unexpectedly of cancer. This terrible disease stands almost alone in that it marks out its victim months in advance. A person who has an incurable cancer is a person whose death may be predicted with certainty and its date fixed within comparatively narrow limits.

“And now observe the remarkable series of coincidences that are brought into light when we consider this peculiarity of the disease. Mrs. Wilson died on the twelfth of March of this present year. Mr. Jeffrey’s second will was signed on the twelfth of November of last year; at a time, that is to say, when the existence of cancer must have been known to Mrs. Wilson’s doctor, and might have been known to any of her relatives who chose to inquire after her.
