The second unabridged release of the classic William series.
It was on Christmas Day that the centipede appeared on Aunt Evangeline's plate, the library clock was found mysteriously dismantled, and the conjuring trick with the egg went disastrously wrong. But as William's Aunt Lucy told him, "A Busy Day is a Happy Day" - and William is always eager to please adults.
The terror of the Brown family is back, leaving a trail of havoc behind him - with the very best of intentions.
