New Hotel Russell

There is a great mystery about the Hotel Russell. Lady Mallory, owner of the famous Hotel Russell, passed away a few years ago without heirs and since then the hotel has been closed. A few months ago the luxurious hotel was bought by a magnate who has decided to modernise it, by installing electricity and telephone lines. During the construction work it was rumoured that Lady Mallory kept her most expensive jewellery in the hotel. Many workers searched for them during the restoration, but they never turned up. Soon the hotel will reopen and it will no longer be possible to find out if the hidden jewels are really there. You are a group of thieves who have been hired to search for the jewels before the grand reopening. Will you manage to find them before you are caught?
