Mr. Longué, aged 79, is offered a life annuity on his provincial estate by his nephew. He receives the same, but more advantageous, offer from his insurer, but Mr. Longué has decided to undergo a rejuvenation treatment in Switzerland, at Dr. Koranoff's establishment. The effect was striking, and he was given a new lease on life, leaving his heirs and insurer in complete disarray. His wife, witnessing her husband's metamorphosis, also undergoes the treatment, and off they go on a second honeymoon to Italy.
