In solid mansions, as a rule, there are always hidden safes. If the owner can afford the maintenance of a large house, he probably has savings, jewelry and other valuables that he prefers to keep in a safe place. The hero of the story The Lost Key - a man who is not poor, who has an impressive account in the bank, keeps some of the money in the safe. Even during the construction of the house the owner installed a safe safe and hid it well. The safe opens with the help of a code and a special key, which the hero always carried with him. But recently he discovered that the key was gone. This alarmed and made you nervous, but while raising the alarm early, first you need to thoroughly search the house, perhaps the key somewhere lies quietly.
