Lucifer

Lucien walked home, his mind lost far away. He did not know what the old man had written to his brothers, but the task that the man had left him ate away at him. Only he was the one who knew how vast his grandfather's financial portfolio had been, to have been able to finance so many of their relatives. 

As his financial adviser, he also understood that he had sometimes invested on behalf of some other people as well. And he'd managed to close those accounts. All but one. 

While Elijah Frost had made all his bequests clear in his will, letting everyone know about their gains and losses, he'd left a responsibility to him. It was a single name and an account number, where he was to deposit money every year. A considerable amount for the next ten years.
