Dez Limerick has his considerable skills pushed to the limit when, to rescue a friend, he has to get to―and get into―a state of the art facility on full lockdown, with considerable forces determined to stop him.

Desmond Aloysius Limerick―'Dez' to all who know him―is a man with a shadowy past, certain hard-to-replicate skills, and a reputation as a good man to have when the going gets tough. Dez is doing his best to enjoy his retirement, wandering the country, doing what interests him, and occasionally helping friends when they find themselves needing any of his particular skills―mundane or extraordinary. For Dez was trained as a 'gatekeeper' - someone who can open any door, keep it open, and control who does and does not go through.

It's those skills that are now in demand when the State Department comes calling looking for his help. A multinational scientific research facility on the coast of Newfoundland has gone dark, the facility on full lockdown, and no one can get in or out. No one knows what is going on, but it can't be good. And a close friend of Dez is presumed locked inside the facility along with everyone else.

Even getting to the facility is an insurmountable challenge. The weather has flights grounded, some shadowy group is doing everything they can to impede the rescue team's progress, and hidden enemies are embedded in the rescue team. But anyone who thinks this is more than one man can face has never met Dez Limerick.
