As two Americans holidaying in Europe, Frank and Janet's greatest fear is to look like tourists. They don't realise that there's more than first impressions to be afraid of. That worse than city rats lurk in the streets. That a single wrong turn in a strange new place can have disastrous consequences. A suspenseful, captivating thriller across the cobbled stones of Rome and Edinburgh, American Innocents turns the dream vacation into every traveller's worst nightmare.
