In this number-crunching thriller, there's something rotten going on in state politics and an unlikely spreadsheet-wielding hero will need to step up to uncover the truth and protect the disadvantaged - but at what cost?

Frances, a public servant, is struggling to come to terms with the disappearance of her colleague Eric, and the death of her brother. Asked to review Eric's last work file, Frances becomes an accidental sleuth, analysing spreadsheets and reports for clues that may help solve Eric's mysterious disappearance.

As Frances uncovers a trail of corruption that leads to the highest levels of government, she must use her wits and resourcefulness to stay one step ahead of those who want to keep the truth hidden. But will her personal vendetta lead her straight into danger?

With twists and turns at every corner, this is a must-read for mystery fans from the bestselling author of The River Mouth.
