At the other end of the scale a professional burglar, Leopold Socha, hid twenty-one Jews in the Lviv sewers, which he knew well having used them to stash stolen goods. For fourteen months he brought food every day – including a bottle of vodka to celebrate Stalingrad – and arranged for the weekly laundering of their clothes. He produced a Jewish prayerbook, and provided potatoes instead of leavened bread every Sabbath.
