Arsenic for Tea: A Murder Most Unladylike Mystery
My favourite character in Arsenic for Tea (apart from Hazel) is Beanie. It was really funny when she found a very important clue but she was too afraid to look at it. It was also very funny when the author's description of Beanie, when Daisy was telling Beanie about the medieval torches, was hilarious!
I have also read all the other books and I love them.
