One weekday, a mysterious man on the phone claims to have the scoop of his life for Zacharias Brecht...
Even before the investigative journalist can meet the caller, he is murdered. Fortunately for Brecht, he left a mysterious diary full of formulas and notes. A ruthless hunt for that book ensues, in which Ostend, Leuven and the idyllic Wilderen in Haspengouw are portrayed. A matter of life and death is at stake.
Will Commissioner Bottu be able to unravel the mystery before more people are killed?
