Scarlet ‘Cairo’ Sloane fired up another Dunhill and waved out the match. Beyond the Escalade’s tinted windows the busy streets of Karachi’s Noor Jahan Market district buzzed with life under the baking Pakistani sun.She blew the smoke into the SUV’s cab, drawing a weary glance from her superior officer, Captain Clive Hudson. Taking the hint, she lowered the window an inch and redirected her exhaust fumes into the street outside.As a freshly-minted lieutenant she had transferred out of the Parachute Regiment into the Special Air Service only three months ago and she was still finding her feet in the distinct atmosphere of the world’s most elite Special Forces Regiment. Hudson had worked hard to fit her in, but the note of recommendation from her CO in the Paras — Major Richard Eden — had sealed the deal among the others in the squad. There weren’t many people in this close-knit world who had not heard of the notorious Cairo Sloane.
