Graham Greene is frequently included in "novels everyone should read" and "best of the century" lists, and I've been meaning to read him for years. But I'd never made it a priority ... until I found out that Colin Firth narrates this version. This short novel might not hold the broader appeal of the other novels on this list, but I found it enjoyable and thought-provoking, and Firth's narration is pitch perfect. If you love Brideshead Revisited, read this immediately.

From the publisher: "Experience the thrilling search for the Third Man as you follow Harry Lime through the gloomy and treacherous streets of Vienna, a city divided by war and corruption. This undisputed spy classic is now available for the first time with video and photography from the film that inspired the novel."

From the publisher: "James Wormold, a cash-strapped vacuum cleaner salesman in Havana, finds the answer to his prayers when British Intelligence offers him a lucrative job as an undercover agent. To keep the checks coming, Wormold must at least pretend to know what he’s doing. Soon, he’s apparently deciphering incomprehensible codes, passing along sketches of secret weapons that look suspiciously like vacuum parts, and claiming to recruit fellow operatives from his country club, all to create the perfect picture of intrigue. But when MI6 dispatches a secretary to oversee his endeavors, Wormold fears his carelessly fabricated world will come undone. Instead, it all comes true. Somehow, he’s become the target of an assassin, and it’s going to take more than a fib to get out of Cuba alive. Her Majesty’s man in Havana may have to resort to spying."
