When the normally reliable Mortimer Pollock goes missing, amateur sleuths Jonty Stewart and Orlando Coppersmith are called in to investigate. But the country is at war, time away from secret duties is scarce and edicts come from on high not to get involved. Then a dying man insists on Jonty’s father being informed of his death, an apparent accident that appears less accidental by the moment. Are the two cases related, will the combined Stewart family resources be up to the task and who is leaving a distinctive trace of perfume behind them?
