Babson, new here but well-established in England, arrives with a tidy little thriller that endows the usual terrorist formula with an extra flicker of human interest: the villain/hero is an Irish terrorist whose vendetta seems more personal than political--and his bomb-carrier is a five-year-old girl whom he has kidnapped. Their destination? The parade in honor of the new Lord Mayor of London. So the narrative shifts around from the would-be assassin and his captive to the frantic child's mother, the law, and the target--the Lord Mayor. The crowd scenes and parade descriptions grow repetitive, the characters are hardly more than sketches, but Babson manages to keep things swiftly paced and moderately stylish right up to the rather predictable finish. Serviceable.
