Ludum Dare 44 - Merchants

As a good husband you support your wife in her dreams... and more recently this dream has to do with burning down everything she gets. Help your wife achieving her goal by giving her the firewood she deserves, otherwise she'll die of her broken heart.
Travel four cities and exploit the differences in the wood prices. Use undercover networks or nearly legal price manipulations to your advantage. Deliver the wood in time to your wife and help her starting as much fires as possible.

But beware. There are robbers on the streets between the cities. As long as you have gold, they will just take that. But if you run out they will have to kill you to teach you a lesson. Stay away from them and the cold water!

If the robbers don't get you they will participate in educational programs to be better robbers and get you next time.
How many fires can your wife begin with your help?
