''Dear Diary ,

Only a few days left before the end of the summer campus ! Charlotte , Deb , Pilar , Sunny and I are trying to make the most of it ! Today , we went to visit the huge Vatican museums , then we had lunch in the very colorful district of Trastevere , where we tasted a delicious tiramisu (the restaurant owner gave me the recipe , which I can't wait to try !) . But that did not make us forget our project ! As the final details have been settled , I would say that our magazine is ready to be presented ! By the way , the girls want me to do it ! I would really like it , but I'm afraid I won't be able to overcome my shyness ! Can you imagine , I would have to speak in front of dozens and dozens of students ! I'm afraid my legs are starting to wobble and I can't utter a word ! What to do ? I don't know what to do...maybe a little walk will clear my mind...

See you later ,

M.R.''

Colette : Prettypleaseprettypleaseprettyplease! Read more few pages , Vi !

But when Violet turned the page , she found only blank pages .

Violet : The diary ends there ! There is nothing else !

Dina : That means we'll never know how our seniors' summer ended ?!

Paulina : I have an idea ! We could try looking for M.R. , Pilar , Charlotte , Deb , and Sunny , and suggest they all meet up in Mouseford Academy ! They could then tell us the end of their adventure themselves !

Colette : That would be wonderful , but...how do you locate them ?

Nicky : Hopefully , we can do it ! Just work as a team ! And in this , we are unbeatable !

In less time than it takes to tell , the eight girls decided to involve the boys in the search for these mysterious heroines . As the task was difficult , they divided into three groups . Dina , Nicky , Violet , and Craig would comb through old academy records , while Paulina , Tanya , Connie , and Shen scoured social media for any clues as to the identities of the five strangers . The last group are Pamela , Colette , Roni and Vic .

Pamela : As for us , let's pay a little visit to the Flying Dutchman !

M.R.'s account did indeed mention that Sunny had won a major regatta , and they hoped that a rodent frequenting the restaurant remembers her . Casimir Whale , the owner of the restaurant sees them arrive .

Casimir : Welcome ! Could the mistral have brought the good smell of our special fondue to the academy ?

Colette : That's almost it ! Ha ! ha ! ha ! We would like to try it , but we came for something else...

Roni : We are looking for information on the winner of a sailing race that took place fifty years ago .

Casimir : I know who can help you !

He pointed to an old fisherman engrossed in his papernews .

Casimir : Oswald has a memory like an elephant !

And he was right , the old rodent proved to be an inexhaustible source of valuable information .

Oswald : Of course I remember Sunny ! She is a very playful girl and an accomplished sailor ! Come see this wall . It is covered with pictures of old regattas . Maybe one of them can be useful to you .

The students followed Oswald and their hopes were not disappointed .

Oswald : That's her !

He handed them a picture of a young mouseling proudly brandishing a cup .

Oswald : Her name is inscribed behind the photo .

The students thanked Oswald . Then they set out to go back to the academy to inform the other two groups of their discovery . At the same time , their comrades entered the restaurant .

Roni : We found Sunny's last name !

Nicky : And us Charlotte and Deb !

Tanya : And here is Pilar's address !

Tanya held up a sheet she had just printed . The members of the two poetry clubs exchanged disappointed looks , however , no one had managed to identify M.R.

Colette : Don't worry ! We will simply ask Charlotte , Sunny , Deb and Pilar to warn their friend !

Violet : That's right ! What are we waiting for ? Let's hurry up with our invitations !
