Trevayne

Jonathan Ryder (Robert Ludlum pseudonym) · Delacorte Press · 1973

The 1973 Delacorte printing credited to Jonathan Ryder is the genuine first. Ludlum used the pseudonym because a novelist was not then expected to publish more than one book a year. The novel was later reissued under Ludlum's own name (1989); that reissue is not the first.
