Nightmare, with Angel — Stephen Gallagher

After rescuing Marianne Cadogan from an incoming tide on a lonely and forgotten part of Britain's coast, ex-con Ryan O'Donnell is cornered into helping her escape a supposedly abusive father to reach the safety of her mother.

Too late, he finds himself compromised, the subject of a trans-European manhunt while he struggles to deliver the child and prove his motives pure/

The deeper in he gets, the more trapped he will become.
