ADDED: see my other comment, sometimes it gets bogged down in detail for non-specialists, or discusses intrinsically boring theaters, but much of it is riveting, and you sort of need to read the whole account, e.g. the story of Juan Pujol García AKA GARBO (https://en.wikipedia.org/wiki/Juan_Pujol_Garc%C3%ADa) starts very early in the war, when in Spain, on his very own after his offers to help were rejected by the British and Americans, he started running his own deception operation and got accepted as a German agent. Per Wikipedia:
He was instructed to travel to Britain and recruit additional agents; instead he moved to Lisbon and created bogus reports from a variety of public sources, including a tourist guide to England, train timetables, cinema newsreels, and magazine advertisements. Although the information would not have withstood close examination, Pujol soon established himself as a trustworthy agent. He began inventing fictional sub-agents who could be blamed for false information and mistakes.
The Allies finally accepted Pujol when the Germans spent considerable resources attempting to hunt down a fictional convoy. After the initial interviews carried out by Desmond Bristow of Section V MI6 Iberian Section, Juan Pujol was taken on. The family was moved to Britain and Pujol was given the code name "Garbo". Pujol and his handler Tomás (Tommy) Harris spent the rest of the war expanding the fictional network, communicating at first by letter, to the German handlers and later by radio. Eventually the Germans were funding a network of twenty-seven fictional agents.
Only guy to get high decorations from both sides; in The Deceivers you'll find out how the British realized something was awry from mistakes made in the info he was sending the Germans, and as noted above, brought in from the cold. He later played an important role in fooling Hitler about D-Daym wrote him a magnificent letter about how important it was to not get the response to the invasion wrong.
There is also a very detailed (and difficult to read, but interesting) book by Thaddeus Holt called "The Decievers" and various books by Ben McIntyre are very good pop-history.
But I found e.g. the account of Operation Bodyguard (https://en.wikipedia.org/wiki/Operation_Bodyguard), the "Bodyguard of Lies" that shielded D-Day, to be riveting, as you'd expect from what might be the greatest strategic deception in history.
(btw the Operation Bodyguard article isn't in the best of shape, although I've been working on it on and off. The sub-plans [Copperhead, D-Day naval deceptions, Ferdinand, Fortitude, Graffham, Ironside, Titanic, Quicksilver & Zeppelin] are in better shape. My favourite is Copperhead.
Not sure about his not giving enough attention to other theaters, besides the Pacific for the mentioned reason, but my copy of the book is packed away in preparation for a move. I don't remember him ignoring any of them, except maybe attempted actions against the Italians.
Duff Cooper was a diplomat who had held several top level posts during the war. In 1950, he published a spy novel, Operation Heartbreak. The key plot device was floating a corpse into Spain with false documents to deceive the Germans. Cooper had come up with the idea on his own, but naturally, many of those concerned with Mincemeat (including Germans and Spaniards) became concerned and started talking. The 'flap' attracted the attention of the British press and wild rumours began to circulate. At this point, the British security services decided that the best response was to publish the story of Mincemeat, which would not compromise any other secrets. Ewen Montagu took a weekend off from his busy legal practice and wrote the book The Man Who Never Was. It was an immediate best-seller and was made into a movie of the same name two years later. The movie added some fictitious elements for drama, such as a German agent in London verifying the background of "Major Martin", with Montagu and his colleagues one step ahead of him.
In 1977, Montagu published a second book, Beyond Top Secret ULTRA, in which he recounted his secret war work. It could not be revealed earlier, as it involved both Ultra and the Double Cross System. In chapter 13, he gives a short version of the Mincemeat story, including some details not in The Man Who Never Was.
As noted/implied above, anything written about WWII prior to that point in the '70s when Ultra could be talked about has to be taken with a grain of salt/suitable adjustments.
