Cold Monday — Terence Strong

Haunted by the brutal murder of his wife in Bosnia, an ex-SAS soldier promises to track down the culprits and avenge her killing.
Just when his life is going into meltdown, a former colleague tells him one of the killers is in London â€" and there's already a contract out for the man's assassination.
What he cannot know is the elaborate game of bluff and counter-bluff being played out in Europe for the biggest stakes imaginable. There are high-ranking officials and politicians who have a vested interest in his failure and disappearance.
So begins his dangerous journey into the dark heart of modern Europe, where he finds himself in deadly conflict with the new mafias and the unaccountable security apparatus of an emerging super-state.
At the centre of everything is a secret act of national betrayal that is as shocking as it is unexpected. All that is required to bring it to fruition is to silence one man.
Unluckily for those architects of treason, that man is in no mood to compromise.
