Read it through once

ADAM. O unhappy youth, Come not within these doors! Within this roof The enemy of all your graces lives. Your brother—no, no brother, yet the son— Yet not the son; I will not call him son— Of him I was about to call his father, Hath heard your praises, and this night he means To burn the lodging where you use to lie, And you within it. If he fail of that, He will have other means to cut you off; I overheard him and his practices. This is no place; this house is but a butchery. Abhor it, fear it, do not enter it.
