Mending Stuart's Leg

Mr Wainwright is back in town, and quickly throws the trio out of the library. The trio goes back to the cafe, where Ivy is having the usual battle of wits with Sid. There they meet with Stuart, and old man who's having a strange click in his leg. Later the trio helps Sid to mend a whole in the roof of the cafe with the usual disastrous results. Meanwhile Wainwright dates the new female librarian.
