The Skeleton is trickier than ever this week! I got Swinburne the poet sometime ago, but there's one
crossing it that I can't see. 11 Across is:- "Foreign lady Ian described". I can only see this as "LIBYAN" but can't fully parse it. Also, for 17 Across, ("Criminal caught on the way to a castle") I put "CONWY" (CON + WY which is an abbreviation of WAY).
For 28 Across, ("Plant consisting of two leaves") I can only come up with "FAITHLESS" but I can't see it.
Also I haven't solved 5 Down ("A metal weight is present")
and have H--T for this.
