The second book of the series Donovan

Private investigator Mel is looking for David, the baby entfühten her friend Rose. Because no really hot there are tracks, Rose has now set his mind to take a medium to help. Since Mel does not believe in such a 'transcendental nonsense' she goes so only grudgingly.
Sebastian Donovan's a witch and has clairvoyant abilities, and after he has just cleared a series of murders in Chicago do not really feel like Rose and Mel to help. That a look at Mel convinced him otherwise, I think is clear.
Quick Mel realizes that Sebastian is what he says, and then the two can begin their cooperation to child trafficking in a case.
