Ross' series featuring British SIS agent Marcus Aurelius Farrow is hardly known in the U.S., so few readers here will be familiar with Farrow's much-referred-to previous cases--which, if they're as mechanical and thin as this one, may be just as well. Farrow, yearning to retire, is cajoled into yet another assignment: knocklng off his archenemy, KGB super-agent Anna Serov, while she is rendez-vousing with an IRA villain in a Spanish hideaway. So Farrow sails for Spain and, on the way, teams up with a comely CIA agent--who is also on the Anna Serov trail. And, by the time that Farrow has his showdown in Burgos with Anna S., he has wrangled with local fascists and captured a local communist--whom he can exchange for his CIA lady, who's been nabbed by the KGB. The mission accomplished (it's the CIAwoman who actually does the killing), all that remains is to escape from Spain in the trunk of a car. Dehydrated James Bond-ing--inferior in all respects to such classier SIS types as Ritchie Perry's Phills (see p. 714).
