Congratulations to all the class detectives who tried to guess who our mysterious writer was from the message left on our blogger. Most of you are on target. Lou has even gone further when she found the poem online. By the way, Dennis wrote to me and asked me to post his answer but I'd rather he did it himself, so I am going to wait a little bit longer until he returns home from England.
As for vocabulary doubts that appeared -
Françoise - the word you need is deliberately, on purpose
Katherina - fantasistic does not exist - you could use unlikely, improbable, far-fetched.
