Unlike the first Raddall title from Harlequin, Roger Sudden, there is no notice that the work is abridged. But a comparison with the New Canadian Library edition published in 1963 shows the Harlequin has less pages, less lines per page and less characters per line. The full effect is about 15% less novel.
I haven't read the book but my guess is that the heroine depicted on the Harlequin edition isn't what Raddall had in mind. The book is available from the Halifax publisher Nimbus.
