One day, three police officers came to Comboni College asking for a favour from Fr De Bertolis, our superior. They had a suitcase with a code lock and they had forgotten the code to open it. They had gone even to the prison to ask some skilled burglar to open it, but in vain. After hearing there was a missionary in Comboni College who knew how to handle anything mechanical, they had come to ask if he could open the suitcase for them. Bro. Soardi was immediately called for. He came, asked silence, and with much patience started moving the number spins. One by one, he found the numbers of the combination, and got the suitcase opened. The three officers would not stop thanking such a clever engineer.
