Lincoln Blackthorne is an adventurer on a global scale.
Blackthorne is described as a misfit spy in at least two flyleafs, though for which organization it is not clear. What is clear is that he is a very experienced adventurer, also described as a combination of Rambo and Indiana Jones with some Woody Allen thrown in. He is described as average in height and slender in build with unruly black hair and "eyes so dark they saw through the soul".
Blackie, as he is called although he hates the nickname, is fair with his fists, good with guns, great with knives, and very bad with heights. He is definitely the man to call when you need an artifact that doesn't want to be found or that is being held by people who really want to keep it.
When he is not out adventuring, though, he is happily working in his tailorshop in Inverness, New Jersey, where he lives a very sedate and uneventful life. He is being persued for marriage by the young and lovely Carmel and entertained by three old folks who like to hang around the bench outside his shop.
What makes this noteworthy is that these old people, a woman and two men, obviously have a history with him and with each other. The woman, Old Alice, is an expert forger and the two men, Macon and Palmer Crowley, are adept at creating weapons and strange tools used by Blackthorne in his adventures. This is a very interesting group.
The adventures that Blackthorne takes part in are the reason he is included in this listing for while they do not include international intrigue or actual espionage, the people he meets and often fights do those jobs routinely and apparently at one time so did Blackthorne. And these books are just too good to not put in.
