Ok, I’ll admit that I really like a good mystery and adding a psychological twist or a scientific / medical dilemma, like Cook’s novels usually have, intrigues me even further. Intervention, however, seems to be a thinly veiled diatribe by Cook about any medical practice outside mainstream Western medicine. He weaves together, and not very well, his vendetta against chiropractors, Eastern medicine, and good old herbal antidotes (anecdotes?). Now, having a chiropractor snap my neck so loudly that there was a sudden silence from the waiting room on the other side of the door put me off that form of therapy and I realized after the fact that the fine print I’d signed absolved him from a possible lawsuit if I’d had a stroke, which I didn’t. However, I’ve found pain relief from massage, accupuncture, and chamomile tea, although not all at the same time. Back to the novel, if you can call it that. Cook is so busy slamming any practice outside his own training, that his plot and characters completely derail. Will I buy another Cook mystery. Maybe. Will I recommend this one to anyone? Not at all.
