Ibn-e-Safi was the original author. Mazhar Kaleem,Safdar Shaheen and a plethora of other writers produced knock-offs of the Imran Series. There was a day light difference between them and the original despite the same characters and being set in, more or less, the same universe. I've read both Ibn-e-Safi and Mazhar Kaleem so I'm doing a small comparative analysis underneath.
MK's Imran was a very cruel character. During interrogation, for instance, he would lacerate a chair-bound suspect and sprinkle salt, spices and lemon juice into his wound and eyes. Or he would promise complete immunity to the suspect (if he confesses) only to later shoot him and throw his body into a '
barqi bhatti' (Electric furnace).
Those knock-off stories were also highly action-oriented with plenty of explosions, gunfights and high-tech gadgets. Poker and Bridge games would often end up in a pile of dead bodies. High-octane stuff and very enjoyable if one's looking for fast-paced literature. Somewhat analogous to movies like Rambo, The Expendables etc.
Ibn-e-Safi's Imran series, on the other hand, read bit like a John Le Carre novel. Slow paced, lots of dialogue and intelligent conversations, very humorous and little action. Very often, a conclusion to the story would be reached after four novels (or sometimes even more). So you couldn't pick up a random novel and expect the plot to make sense.
Ali Imran was a hilarious character. He would act all dim-witted and stupid in front of his Secret Service colleagues. But he also commanded them as X-2, the Chief of SS.
Interestingly enough, none of his colleagues were aware of X-2's identity so the dual cover worked beautifully for Imran.
Imran was a fast-learner and very observant. He used to dodge bullets for fun, a skill he learnt by observing his arch-nemesis Sing Hee doing the same.
Julia Fitzwater, Theresia, Black Zero, Jameson and Zafar ul Mulk..... brings back a lot of old memories
Wow! That's an amazing collection you got there! For some reason I always read him as Prince of Dhimp instead of Dhump.
I have seen Jackie Shroff's Hero and that Lambi Judai song by Reshma is one of my fav i still listen to it sometimes i remember had the music of this song as my phone ringtone for a year or 2 back in 2005-06
