This novel of detective story doesn't imbue the readers a feel of major sudden twists or shocks. Jonas Piedmont Beaumont and his partner/wife Melissa Soames have just seemed to follow the normal investigative routine or the orders of the Attorney
General (Ross Connors) in all their executions. I don't feel that Mr. and Mrs. Beaumont have done anything that was out of the ordinary. I feel that any detective would have done just the same. I guess they don't give the readers any impression of strong or special characters.
Many things have happened and the details have been discovered and revealed by the authorities (police or medical examiners etc.) gradually. One probably couldn't guess from the beginning what would be disclosed at the end. Nevertheless, one doesn't feel that there have been any surprising or shocking twists in the 344 pages. On one hand, everything is like completely credible and it's just like a casual story told by your neighbours; on the other hand, even though various interesting and unexpected developments have occurred, there seems to be a mood close to lack of excitement.
In other words, it's a detective novel easy and smooth to read but you shouldn't expect too much undulating emotion.
On p.61 (lines 8-9), Gerry Willis said "Giselle and Zoe, are only a couple of years older than my grandson", but on p.237 (4th line), we read "Zoe had been younger than Josh". Obviously, there is a contradiction / mistake that the author has made.
