I first read this novel about 55 years ago. I liked it then, but I've read it again recently & I underestimated it; it is essential 1940s/1950s fiction. In the last month or so, Stella Gibbon's "Westwood" has been reprinted & Elizabeth Bowen's "The Heat of the Day" has been serialised on the radio. Of the three, the Bowen is perhaps the best novel; again, having reread it I realise it is better than ever I thought, but for me the Balchin is a more enjoyable read. The Gibbons is set in north London in wartime, but the story lacks the essential focus of time & place which the other two novels have in spades. In "The Small Back Room" Sammy is working in a poorly defined Boffin's department testing & analysing the performance of new weapons. An aluminium prosthesis replaces one foot which he lost long before the war; it is a psychological & physical handicap which he finds more & more difficult to cope with in his personal life with Susan, who he will not marry & his professional life which involves field trials & investigations. His department is a bee hive of conflicting interests; the military, the politicos, the academics & the boffins rarely see eye to eye. Sammy becomes involved in the defusing of a particularly nasty German anti-personnel mine which kills whoever comes near it, including professionals from the army. The last part of the book is a wonderful account of how he defuses one, depending upon the physical strength of a senior professional army officer to finish the job. This description of the mutual respect & cooperation between handicapped Sammy & a very strong & fit officer is a brilliant contrast with the green house atmosphere of the government department in which he works. This is essential reading!
