Una has always been more comfortable working with numbers than people.

As an actuary for an insurance company, her job is to spot patterns that other people might miss. When the data for her latest project - into the predicted number of deaths in seaside resorts - shows a blip in her forecasts, Una's untarnished reputation at work is at risk. That is, unless she can work out why there's been an unusual spate of accidental deaths by the coast.

Death by Hanging Basket? She's not seen that before. Where better to begin than her mother's hometown of Eastbourne, where strange fatalities are befalling her mother's bingo crowd. But as Una puts her spreadsheets aside and begins to investigate, a sinister pattern begins to emerge and she realises that there is nothing accidental about these casualties...
Can Una stop the killer in this small seaside town, before she becomes a not-so-vital statistic?
