ACE Spencer Dunmore. Toronto, Lester & Orpen Dennys, c1982. 261pp, cloth, $16.95. ISBN 0-88619-018-5. Grades 8 and up. Reviewed by Alfred F. Greenwood. Volume 11 Number 1. 1983 January. Born in London, Spencer Dunmore was educated during World War II, came to Canada in the mid-1950s, and now lives in Ontario. He is a week-end private pilot. Previous books include Bomb Run, Towers of Strength, Collision, Final Approach, Means of Escape. Ace is the story of a young German fighter pilot, Ernst Brehme and follows his career from the beginning of the war to just short of total defeat. Ernst is handsome, skilful, and dedicated, becoming one of the most decorated and publicized fighter-pilots in the German air force. Predestined to marry his childhood sweet-heart, he falls in love with a Jewess. Dunsmore spins a good yarn. Characters are defined, and the story line well developed. Action scenes, and there are many of them, from Britain to Russia, and fast, crisp and believable, delivered in a staccato prose that lends excitement. The author's extensive knowledge of German aircraft shows thorough research into his subject. This knowledge leads occasionally to redundant trivia, i.e., in the 109 G "The compression ratio has increased: 7.3 for the port cylinder and 7.5 for the starboard block." It's a minor fault. Ace is one of the better works of fiction for the war book shelf. Alfred F. Greenwood, Victoria, BC.
