Note:

Prior to its publication in book form, an abridged version of The Eagle's Shadow was published in nine parts, appearing in the August 6 through October 1, 1904 issues of The Saturday Evening Post. Each installment was profusely illustrated by Will Grefé. Two of these drawings were later reused as the two different frontispieces for the first printing of the book, and seven others were used as illustrations in it.
