The Lonely Silver Rain (1985) is the 21st and final novel in the Travis McGee series by John D. MacDonald. The work was published a year prior to the author's death, and was not intentionally the end of the series. It is also notable for the introduction of McGee's daughter Jean, who he unwittingly sired with the now-deceased love interest Puss Killian from the ninth book in the series: Pale Gray for Guilt. At the end of the book McGee has taken all of his cash in hand except for a few hundred dollars and placed it in a trust fund for his newly met teenage daughter, and needs to go back to work as a "salvage consultant." The author's death prevented any further development of this new character and plot line. Source: Wikipedia (en)
