I think the question is whether Harry splurges on nice stuff or if he falls back into what's familiar and furnishes the castle via Goodwill [/list]
I doubt he'll splurge. I'm a little surprised he said something about "with what money I have left" or something along those lines at the end of Battle Ground. He should have his and Murphys diamonds, which should be a lot even after the weregild to Marcone.
I see him going a frugal but sturdy route. No doubt Michael will know someone in the wood furniture business that will build solid good furniture for a decent price. Because Michael.
And even if he has to buy it, I'm sure he'll get decent stuff. It's no longer about being a poor detective wizard. It's about making a home for his daughter and a sanctuary for the apocalypse.
