Final Chapter

"De parvis grandis acervus erit"

We are reaching the end.

Our experienced security and intelligence team (they really exist), have been following the strange behaviour
of a couple of bankers who may be involved in a conspiracy plan against the dead girl by hiring a hitman.

Those bankers have been using a well-known technique called Salami slicing.
They have been collecting money using discounts calculations coming from lots of invoices
during the past months without being noticed and caught. Then, they have successfully sent
a huge payment to another account to pay for the crime.

Our intelligence researchers have stolen this transaction logs:
A database schema of all the transaction tables and 5 datasets: a, b, c, d, e.

We know for sure that the amount of the transaction is somewhere between 10.000 € and 12.000 €,
so we made a list of all the registered movements. It must be one of them.

Figure out the correct amount of money that has been transfered and discover the identity of the real murderer.
Send a message to 689168478 using Signal with your name, the name of your group, and the correct answer.
If it's correct, we will send you something back.
You only have one chance, one message. Just the first one will count, the rest will be ignored.

--------------------------------------

In order to help you a little bit we have also extracted a smaller dataset as an example from
another similar case with the correct result: A database schema of all the transaction tables and 5 datasets: a, b, c, d, e.

The correct sum of the bills is 1.392.964,84, but the salami sliced amount is 1.392.960,00 €, so in this case they have stolen 4.84 €.
