The Head in the Soup — Peter Levi

Two men were murdered because they knew the secret. The secret that had been kept for two thousand years! There is nothing more deadly than gold. Men will beg for it, steal for it, kill for it. And when the gold is the missing treasure from King Solomon's Temple, whole nations join in the madness! Gold is powerful. It can make missiles vanish from their factories and reappear in small war-torn countries. It can make a sane, well-balanced Oxford professor into a ruthless fighter. It can alter the whole balance of power in the Middle East. Gold is the ultimate weapon!
