The first two novellas were followed by The Castle of Iron (April 1941), which took Harold to the world of Ariosto’s Orlando Furioso. Also in that year, Holt brought out the first two novellas as the clothbound book The Incomplete Enchanter, which has since been through a number of editions. While Pratt proposed the basic themes for the first two stories, those for the later ones were worked out by discussion between us.

After World War II, Pratt and I rewrote and expanded The Castle of Iron to full-novel length, in which form it appeared in 1950. We also wrote two more novellas of the saga, placing Harold first in the world of the Finnish Kalevala (The Wall of Serpents) and then in the world of Irish myth (The Green Magician). After magazine publication, these two stories were combined in a cloth-bound volume, Wall of Serpents. It was not possible to include them in the present volume, first because of considerations of space and second because of contractual complications.

For obvious reasons I cannot assess the virtues and faults of these works. I will say only that they were certainly heroic fantasy, or swordplay-and-sorcery fiction, long before these terms were invented. While Robert E. Howard is justly hailed as the major American pioneer in this subgenre, neither Pratt nor I, when we started the Shea stories, had even read a Conan story or ever heard enough about Howard to recognize his name.

Our method of collaboration was to meet in Pratt’s apartment and hammer out the plot by long discussions during which I took shorthand notes. Observing the utility of Pratt’s knowledge of shorthand from his journalistic days, I soon taught myself Gregg and have found it valuable ever since.
