One major subplot of my story involves theft of company funds and assets (mining equipment) by a high level executive within the company. The main character spends her time trying to uncover it and the person responsible. Im trying to figure out a few things. First, how would this scheme initially be uncovered? Maybe through some kind of audit? (I know nothing about accounting). Second (related to above) how would a person steal a lot of money and equipment without being found out? I.e. what type of position would they have to be in? Who would they need as co-conspirators? Third, what type of job would the MC have to have to be in a position to uncover it and as a result become a target for assassination by the perpetraitors? (Note - would have to be emplyee of company, not a cop or something). This is not my area of expertise so any resources you might recommend would also be helpful.
