The Teeth of the Tiger by Tom Clancy

They have adult westerns, so maybe this is supposed to be an adult spy story. Adult westerns seem to drag on as this book does. The book could also be called, "the Making of an Assassin", or in this case two of them. On the one hand, the brothers readily take to it and on the other hand they whine about the right or wrong of it. The dialog seems to be written by adults who think this is how teen-aged boys converse. It could have been a good story if perhaps it had a different writer. If you are looking for excitement, you won't find it.
