** spoiler alert ** This book was a serious disappointment after reading The Beekeeper's Apprentice. At absolutely no point in this book does our protagonist solve any mysteries of her own. Sure, she investigates into a church and uses some of her logical skills to draw conclusions, but nothing is solved.

She is rescued by Holmes after being kidnapped and forced to take heroin against her will. Unfortunately, the rescue happens off camera and the best we get is a brief description from how Holmes found her. The entire incident seems forced and, perhaps, is only present as a means of forcing Mary to better sympathize with the recovering drug addict, Holmes.

There are two mysteries in the book as far as I was concerned. There is the mystery of who is responsible for a series of deaths and an attempt at a murder. There is also the mystery of Margery Child and bruises that suddenly disappear before a religious service.

The former is pieced together slowly over the course of the book and, just when Mary might have enough pieces to put the puzzle together, the solution is handed to the two detectives in a nicely gift wrapped present. Thank goodness the two great detectives didn't have to piece anything out. It might have been the entire reason the reader picked up the book in the first place.

As for the latter mystery, that is answered during the postscript of the book. It is explained as being, "God's Work." Yes, that is right. The two mysteries of the book are solved by being handed to Mary Russel and being answered as "God did it".
