Where can I find a torch? (The Witcher 3: Wild Hunt)

You can buy (there are traders who sell trash, look for them) or remove an enemy (a person of course) you have killed, but why do you need a torch? there is the elixir the cat drank and in the dark everything is visible, but if you set fire to the sign, use the sign, your torch is not a necessary thing, the current takes up space in the inventory))))

In the White Garden, lying in the houses of residents, in Velene - there is a cave under the castle of the baron, it lies there, and even so in the chests you can find it. Very often come across (to me personally) in places "?" I collected 34 pieces

So the fact of the matter is that they used to come across (apparently, he cleaned everything) and now for a whole day, hell .... Name at least one specific merchant from whom you can take, pzhst.
