ninth birthday. Such a happy, exciting day it had been; it felt like a

birthday all day long, so you can guess how jolly it was, and how

special it made Jack and Molly feel. Little did they guess what a weird

and mysterious end to the day was now approaching!....

“Had Aunt Phœbe known when she bought ‘this useful little thing’ what it

Really Was—could she have foreseen any of the mysterious happenings

that were to follow the arrival of her birthday present—she would have

preferred to send her niece half a dozen of the most jingly silver

bangles ever made; for she disapproved of adventures in any shape or

form, even more than she disapproved of bangles. Yet it was entirely

through Aunt Phœbe that Jack and Molly took part in the adventure of the

Grey Pumpkin at all.” - Summary excerpted from Chapter 1 of Knock Three Times!
