Some more awkward writing:
When the DI says:
"The Gill family were going to need a special kind of support, having clearly lost a very special daughter to truly horrifying injuries. Liz had been a twin, too."
You know, because none of the other parents thought their kids were special, and in any case, the other parents would require less support because they'd all agree that the Gill's daughter was more special than anyone else.
A few pages later, we have the following observation:
"Ishbel could identify other Three Rivers family members easily: they were either crying, or looked like they were trying not to. Even the men looked numbed, lost."
Come again? Why wouldn't the men, i.e. mostly the victims' fathers, be affected?
Then, on the same page, a few paragraphs later, the very same character observes about her husband:
"As he neared, she could tell from his face that he'd been crying, too - the whites of his eyes were bloodshot, and his cheeks were read. She hadn't seen him cry thus far: he'd been disturbingly. angrily stoic throughout the process of being told that Abigail was dead, [...]."
So, which is it? Is it surprising that men should have feelings, as Ishbel seems to think in the first paragraph? Or is more unnatural if they don't, as Ishbel seems to complain about in the last paragraph?
This is just stupid.
Actually, the whole book is just stupid.
