A cute little story.
Titus is one smart little corgi!
The Queen is adorable, so is Prince Philip, and as for the corgis? Eek! I love corgis.
There may be some things that children wouldn't properly understand - the banter between "Madge" and Philip being one - their relationship is portrayed in a rather mature way.
I substituted the queen drinking coffee for tea. Obviously. I have a US copy, perhaps it had been edited for the US market.
Overall, a nice little story for children.
