### 183

No matter how hard you prod the slab it shows no sign of movement, but your probing does uncover something previously hidden beneath the dust. Carefully you scrape away the grime until the outline of a coiled snake is revealed, etched deep into the dull grey marble. Carved in the centre of its scaly coils is the number 123. Make a note of this number in the margin of your Action Chart—it could be of use at a later stage of your adventure.

If you wish to jump across the slab and press on into the tunnel beyond, turn to 127.

If you decide to enter the tunnel by walking across the slab, turn to 277.
