What a boring summer it's going to be. But then, lying in bed one night, he hears the old grandfather clock in the hall strike the very strange hour of 13 o'clock. What can it mean? As Tom creeps downstairs and opens the door, he finds out...a magical garden, a new playmate, and the adventure of a lifetime. Una Stubbs stars as Aunt Gwen in this BBC Radio 4 full-cast dramatisation.© and (P)1999 BBC Audiobooks LTD2 h 16 min
