Criminal Investigation Agents: Petrodollars

You take the part of Frances Keegan, an oil industry expert and special agent in the FTB, a branch of the US tax police. The investigation starts when the FTB's surveillance unit spots suspicious movements of funds in the Gold Oil Company's bank accounts and intercepts an encrypted email. To Frances's great surprise, the Gold Oil Company appears to have ties to the wealthy financeer Klaus Fredricks whom Frances's partner, Eric Ward, had been investigating when he mysteriously disappeared nine months earlier.
