Three Girls from School by L.T. Meade

There are at all schools girls of different degrees of talent. There are the brilliant girls, the idle girls, the plodding girls. Now Annie belonged to the middle class. She knew how essential it was for her to work hard unless she were to accept a fate which she considered too horrible to contemplate -- namely, that of companion to kind Uncle Maurice in the country rectory. Her hope was to do so well at school that she might, when she left, induce her uncle to send her for at least a year to Paris in order to put what might be called the final polish on her education. Then, if her present plans went well, she might go into society with the aid of Mabel Lushington, who of course would be from henceforth in her power.

Now Annie had a fairly good gift for writing, and this gift on the present occasion she put absolutely at the disposal of her friend. Poor Mabel, excited by the scheme which Annie had proposed, trembling with fear that it might be found out, could not have written a single line of coherent English were it not for Annie's clearer and cleverer brain.
