When I’ve read too many dark, gritty mysteries it’s always nice to pick up a Mackenzie August book by Alan Lee. They’re strong on tough, fairly clever dialogue, and it’s nice to follow a detective with a positive attitude and faith in God. So we have come to a Dead Stop, book nine in the series.

Roanoke, Virginia PI Mack August is married to Veronica, a beautiful lawyer. She surprises him by making him the gift of a trip on a luxury private train, Chicago to San Francisco. Mack has always wanted to take such a journey, in the spirit of the old Golden Age mysteries, and jokingly remarks that he hopes they’re attacked by bandits. That won’t happen, but what does happen will be about as bad. Fortunately, their friend Manny Rodriguez, a US Marshal, comes along too – though he’s disappointed to be stood up by his girlfriend.

Their quarters on the train are luxurious, the views are majestic, and the service is excellent. The main irritant is that some of the other passengers are annoying – especially a Republican couple and a Democrat couple who can’t stop sniping at each other. There also seems to be a fair amount of sexual hijinks going on.

Then one of the conductors disappears. And one by one, other members of the train’s crew vanish as well, to be found in the snow with bullet holes in their heads. Manny declares “marshal law” and they try to keep the other passengers calm (and away from each others’ throats) while doing their best to identify the murderer in their midst.

Dead Stop is a story with a message, and it’s not exactly subtle. Mack and Manny constantly try to remind their fellow passengers that they’re all on the same train and need each other, while those passengers are consumed with mutual hatreds – political, social, racial and international. The conservatives and liberals are about equally caricatured, so I don’t think anyone should take offense.

There’s a civility lesson I’m not sure I entirely agree with in the final solution to the crime. But all in all, the book was pleasant enough, and more positive than not in its (relatively heavy-handed) teaching moments.

As usual, author Lee could use a better proofreader. A particularly odd word error is when he tells us someone is wearing a “toboggan” on his head. Is there a piece of headwear known as a toboggan? Did he mean “toque?” Another mystery, this one unsolved.
