“But there is yet another coincidence. Jeffrey’s body was found, by the merest chance, the day after his death. But it might have remained undiscovered for weeks, or even months; and if it had, it would have been impossible to fix the date of his death. Then Mrs. Wilson’s next of kin would certainly have contested John Blackmore’s claim⁠—and probably with success⁠—on the ground that Jeffrey died before Mrs. Wilson. But all this uncertainty is provided for by the circumstance that Mr. Jeffrey paid his rent personally⁠—and prematurely⁠—to the porter on the fourteenth of March, thus establishing beyond question the fact that he was alive on that date; and yet further, in case the porter’s memory should be untrustworthy or his statement doubted, Jeffrey furnished a signed and dated document⁠—the cheque⁠—which could be produced in a court to furnish incontestable proof of survival.
