Tell Sackett is definitely an interesting character. The inference could be made that he had a bit of PTSD... and that his decision to fight for the Union had made it impossible for him to return to his previous life and associations.
In the novel Smoky Valley, author Donald Hamilton points out that a temper is something that only the rich or the powerful can afford... with Tell, we learn that a conscience can also be an expensive companion.

I would love to see a Compendium of Tell Sackett novels and short stories, in order as best as can be guessed. The only mention of him that could be omitted would be Dark Canyon... I don't think he has any dialogue in that novel, just has his name dropped.
