He felt oddly naked, ridiculous, as if his exhaustion had cost him all his judgment. He'd essentially stripped himself of his own privacy and dignity to try to impress someone else, for whom it had been, at best, a moment's diversion.

When the author isn't jamming too many descriptors into their sentences, this is really strong writing for a rookie. The use of emotion is very well done, as is the humor and banter between James and his colleagues. And let's not forget the penis trophies. That's all you're getting from me. ;)
There are continuity errors, like James and his boss driving together to the victim's family's house and then leaving separately, or James worrying about contaminating the crime scene with his DNA when he just put on a full-body containment suit. Try to get a better editor next time, yeah?
