When Henry finds a strange baby hidden among the flowers in Aunt Agathas
garden, it looks like another adventure is in store especially when little
Sweetheart sprouts antennae! But when a host of ghostly women begin to haunt
131 Ballantyre Road, all desperate to catch a glimpse of the baby, Henry and
his new friend Rosie know this is a job for the magical, marvellous Harvey
Angell.

Henrys extraordinary friend quickly realizes that Sweetheart isnt from this
world shes from the future, and she needs to get back home before its too
late. That means a breathtakingly dangerous trip through time for Harvey Angell
. . .
