The Keys of Hell by Jack Higgins

A rediscovered gem of international suspense from the man Tom Clancy calls "the master..."

Paul Chavasse makes his living running arms and intelligence from Italy to the oppressive communist country of Albania. But when the Albanian government begins a religious purge, he finds himself in a deadly race to recover a priceless relic that has protected the faithful for generations.

Now he must outrun-and outwit-an entire army to save the lives of thousands of believers.
