A good roll on the
Engagement, this means you have some time to act and are in a Controlled Position for any follow-up rolls (for now).
I don't see any difficulty getting into the manor house, you are professionals and don't need to roll for picking locks or climbing to balconies when you have the time (really, how could you fail?). Once in the house (or when the next obstacle arises) you will all probably need to roll some form of 'stealth', as a Group Action or individually.

A Lantern costs 1 Load, but we only care about things used on the Job. We can ignore the lantern you used in the tunnel, for now. If you need it during the Job you can mark the Load and have it, else we can say you left it below in the tunnel (we won't actually 'say' that though, we can just leave it undefined till it matters). While in a house, there are probably lights you can borrow (no load (unless you take them with you)).
