Dirty War - Stephen Leather

The target - the Prime Minister. The assassins - hard-bitten jihadists with nothing to lose. The only man who can stop them? Dan "Spider" Shepherd. But Shepherd's reputation is also on the line - he helped get one of the jihadists into the UK during the final days of the War in Afghanistan. Now he has to track down the man whose life he once saved. But the assassins aren't lone wolf killers - someone much more devious is pulling their strings. And the clock is ticking . . .
