Issue 18 was the last Princess II to use the Girl II format and newsprint that the series had used since #1. From #19, Princess II switched to the same format, newsprint and page count as Tammy. She dropped the photo stories and the colour pages and became an exclusively picture story comic like Tammy. In so doing, she broke away from being the sister comic to Girl II and became more like the sister comic to Tammy, though she did not say so. She hailed the new look as “great news”, but it was clearly anything but. In fact, it was a sign that she was in trouble and cutting costs. This is particularly telling in her reprinting old serials from Tammy and Jinty. Years later these reprints had the benefit of enabling some of the original artwork from IPC girls’ comics to survive, of which very little has. But at the time, a new comic falling back on reprints from older titles was a very, very bad sign.
As Princess II drops the photo stories this issue, naturally this is the last episode of “The Ghostly Ballerina”. Clare finds a way to lay the troublesome ghost of Arabella Hood and free herself from Arabella’s power: create a ballet about Arabella’s life to give her the fame that her premature death deprived her of.
Also ending this issue is “Fairy Tale”, our tale of mixed-up fairy tales. It gets even crazier with a genie who grants two wishes instead of three, and he is so deaf he often mishears your wishes – to the cost of the evil Morgana when she calls upon him for wishes. The greedy Angie does not emerge from the adventure much improved once the girls return home, though she does get a comeuppance for it.
“Lena Lends a Hand…”, the complete story, is clearly a filler story to mark time until the whole new lineup begins in the new look Princess next issue. Lena tries to follow the Brownie motto and lend a hand one Saturday, but her efforts always keep going wrong – until she unwittingly lends a hand to catch a thief.
Judy Marshall is beginning to unravel the mystery of “The School of Dark Secrets”. The school staff are in some sort of secret occult, and they say their thirteenth sister has arrived, which completes the coven. They are referring to a portrait, and when Judy gets a look at it, she finds it is of a girl who looks just like her!
Grovel is taking delight in spooking everyone with the ventriloquism he has learned from a book. But it isn’t long before Sadie learns to fight fire with fire.
A club called the Treetoppers has formed around Sheena’s treehouse. But someone is spying on them. Is it the snobby Beverley Sneed, who’s already suspicious, or someone else? Sheena soon finds that somebody has definitely been around the treehouse, and they’ve stolen her bike too.
