Another such case is Hugh Lofting, who wrote a Dr. Doolittle book a year from 1922 to 1928, when he sent Dr. Doolittle off to the moon and had Thomas Stubbins come back to Earth without him. After that there was a five-year gap before he wrote Dr. Doolittle's Return. Apparently Lofting had intended Dr. Doolittle in the Moon to bring the series to an end . . . but he didn't succeed.
