Plot[]

Millionaires' Conspiracy[]
In Case 6: An Unexpected Windfall, she helps Katrielle Layton find who stole the 100 million pounds from the bank.
In truth, it wasn't a theft at all: the vault's air ventilation system had malfuctioned the night before, creating an air lock inside the chamber. When Mr. Shinplasters came to open the vault's door, the resulting vacuum was so strong it not only sucked in Shinplasters, breaking his legs and knocking him out, but it also made all pound bills be expelled via the ventilation system out of the building and into the sky, where it then went to parts unknown.
Since such a malfunction was not covered by the insurance, meaning that the bank would have to pay all the missing money, Teller, having figured what had actually happened, thought that it would had been better to pass it up instead as grand larceny, and then resign from her position as compensation for the resulting fraud. However, before such insurance fraud could happen, Katrielle discovered the truth during her initial investigation; Grant Sloanes, her old friend and boss, having managed to retrieve most of the dispersed money thanks to Katrielle's directions, then decided to forgive Teller for the attempted fraud, as the lost 20 million pounds was overall a better price to pay then selling the faulty vault model to other banks and then pay for any potential other incidents. As such, the grateful Teller was able to keep her job as general manager.
