Unfortunately I wasn't able to re-read this one this month, too busy with work and life in general which will also keep me from reading the September selection, but I did enjoy it when I read it last year.
It is interesting that this Jackal is the basis for the real
Carlos the Jackal who got his name because a copy of
The Day of the Jackal was
spotted "near some of [his] belongings." Such a tenuous relationship but the name stuck. Obviously this book had a very large impact on society in the few short years after it had been released for this to occur.
