Dead Straight [EPUB ebook] 

The ad in the Daily Telegraph read: ‘Wanted: a man of resource and courage to act as companion’. Ex-con Macbeth Bain must stay on the right side of the law, and this job seems like the perfect opportunity for him to prove that he can. A woman needs protection from a jealous husband — the only thing is, this husband has been dead for seven months. His phone calls, however, continue unabated, or so the widow maintains. Crazy? Bain doesn’t think so. But it’s not until his third day on the job that the real trouble starts. And when the noose begins to tighten, Bain knows he must break out soon or it will be too late.
