From Casual Debris.
So far the strongest entry of the series. Despite some suspense fiction cliches, Part Five of John Saul's serialized The Blackstone Chronicles is better paced and more focused than the previous books. It is through the focused narrative of this part that I became conscious that the presence of the mysterious, evil figure is distracting, adding little to the narrative, and actually decreasing the mystery element of the work as a whole, and I wonder what kind of read we would have if the scenes with the figure were excised.
Plot-wise, the main focus is on Bill McGuire, who unknowingly takes the cursed gift of a stereoscope into his home. His family is quickly (and forcefully) set up as ultra loving, with overly supportive wife Bonnie and sweet 'n innocent daughter Amy, along with the over-sized loving puppy. (Yes, yes, we can immediately foretell the fate of the beloved family pet.)
Side plots feature Oliver Metcalf learning more about his deceased twin sister's death, and on his wish to exorcise the demons of his past. Whereas Rebecca has been kidnapped and locked away in a cold room of the asylum. As these segments are brief and well interspersed, they come across as more effective than the sub-plots in previous volumes, and do not interfere with the main plot.
This level of focus should have been achieved by part four, since by then the formula of these little books have become too predictable and tired, and thereby part four comes across as the weakest; I for one hurried through its pages and paused before picking up "The Stereoscope." The denouement of "The Stereoscope" is, with slight variation, essentially the same as each predecessor, but does, with its elevated structure, act as a better precursor to the final volume than any of the previous books.
