14 years before, Derek Locke and Eddie Guard conspired to embezzle a fair amount of money from the bank a were employed. Guard, on his vacation, began so set up the Swiss account into which they would move the proceeds; Locke, whose vacation followed Guard's, met him on the intervening weekend to finish that up. Before Derek could return to England Eddie was arrested (the theft had been discovered), and Derek took off for parts unknown.
Flash forward. Derek's (14-yearyounger) brother Jeremy is now a solicitor...and Derek has returned to England, planning to meet up with Eddie and get his share of the loot. And Eddie gets himself murdered; Derek, of course, is the chief suspect--but Derek also says Eddie has told him that a third man as involved.. Jeremy, for reasons that aren't all that clear to me, tries to help him--by finding an alternative suspect and getting Derek out of the country again.
It's not a bad setup, but there are problems (or omissions). First, the embezzlement scheme is not really explained very well. And, more important, there are only two real candidates for party #3. The story moves well and does nothing to make me revise my opinion of Woods as a writer. But it's hardly much more than a little above average for a mystery novel.
