got stuck with 3a-one deity entered Pennsylvania building (6) and 4d- nonsense, one starts with crude laugh (6) and 5d-ruled fad out that's awesome (8). Have "Sylvan" for 3a. but this won't fit with "dreadful" for 5d. Where am I wrong, and what is 4d? 2d- most valuable greeting for new employee (6,5) also eludes me! Any help please?
