I didn't mean that. Sneaking Scouts can be caught. However, if a Scout hides in your castle (having the command to Hide), the occassional horror attacks that result from being horror marked don't work properly. None of the Scouts die. Sending Lesser (or Greater) Horrors to Contract provinces would work, too, except that the Scouts are hiding and thus won't be in the battle, and the horrors aren't able to attack them. And they can't be seen, so probably won't be targeted by mass destruction spells.

Contracts are expensive investments, but they are quite easy to protect. The Horror Markedness, which should make you lose a Contract every now and then as well as giving your enemies a weapon against you, just doesn't work with sneaky units.
