Recently published in the US is Crime and Spy Jazz on Screen, 1950–1970: A History and Discography, by the appropriately named Derrick Bang.
It has 312 pages, and, apparently, devotes more space to John Barry than any other composer in the book!
At $45 it is not exactly cheap, but when has that ever worried anybody who browses on here. :)
There's also a companion book entitled Crime and Spy Jazz on Screen Since 1971: A History and Discography.
