I do not ask why you require a piece of killing machinery as finely crafted as this. I suggest you do the same
~ The Engineer

The Engineer (real name: Habib) is a minor antagonist in the Alex Rider novel Scorpia Rising. Erik Gunter goes to visit the Engineer and buys from him a finely made gun which the Engineer says will be suitable for his job. The Engineer had already attracted the attention of the CIA when their secretary of state came to Cairo and the Engineer, a well known assassin, was busy making a gun. When Erik Gunter begins to get suspicious of its accuracy, the Engineer tells him not to ask foolish questions. Gunter apologizes and shoots the Engineer dead by firing at his head.
