A tribute of Seale by Adam Shatz for MERIP, as fascinating as the man: 

After his studies with Albert Hourani at St. Antony’s, he moved in 1963 to Beirut, where he befriended Philby. (Philby later claimed that Seale worked for MI6, which Seale denied.) It was the Mad Men era of Middle East reporting, a time of high living and high-stakes intrigue. The “Arab cold war” was at its height, and there was no better, or more pleasurable, listening post for a foreign correspondent than Beirut. The correspondent’s calendar was marked by revolutionary conspiracies; many were first reported as rumors, sometimes overheard at the bar of the St. George Hotel, where spies, arms dealers, diplomats and other adventurers gathered at the end of the day.

Great details in there (I never realized he was married to Mahmoud Darwish's ex-wife, who is also Nizar Qabbani's sister) and a fair appraisals of his failings too.
