I believe this has between rejected before for several reasons, one of which is that an Adventurer could assassinate someone and then be two regions away several seconds later.
There are several ways to counter this,
- Force the act of assassination or assault to take up to 12 hours it would drain an adventurer of his hours for planning and execution of the act and leaving him only 4 hours to escape if he could. Or all your hours.
- Unable to travel as you are currently in hiding in hopes guards do not find you
- The concept of being caught could even mean death, such as. Thought you sneaked into the Lord's estate easily you were caught by a nearby guard who quickly subdued you and arrested you finding a poisoned dagger in your cloak." Either way if you're caught and a commoners it would be a sure thing you'd be executed.
