The Penderwicks are back again:
Four girls and their dad.
But going back in time, we'll see
What made them very sad.

When Batty was a tiny babe
Sweet and soft and new,
Her mother became very sick,
But how sick, no one knew.

She loved her husband and her girls
And tried to leave her best
By writing a letter on paper of blue
That would explain the rest.

Aunt Claire kept the letter safe
Until the time was right,
She'd save it for the four girls' dad
To make his future bright.

Four years flew by like blinks in time
And now the time had come.
Aunt Claire would bring the letter of blue
To be read by everyone.
