She wrote to ZAO Learnfast explaining this, enclosing drafts of the three chapters she had managed to complete, together with her invoice for one-quarter of the fee.Three months after entering into the contract with Yevgeni, ZAO Learnfast was advised by the relevant professional body that the subject on which Yevgeni was writing his study text would be withdrawn within a year.
