THIS IS THE SYSTEM OPERATOR. WHO IS USING THIS ACCOUNT? PLEASE IDENTIFY YOURSELF... Vicky's life is completely normal. Maybe even a little boring. But all that changes when her dad is accused of stealing a million pounds from the bank where he works.
Vicky knows for sure that her dad is innocent, and is determined to prove it. Luckily for him, she is a seasoned computer hacker. Using the skills he taught her, she's going to attempt to break the bank's files. Should be simple, right? But it's a race against time to find the cyber-thief, before they find her . . .
