Thirty years later,
Stockwood is desperate to return. He has devoted his life to studying the sacred
stone, and needs to know if his theories are correct. Visiting earth with Leela,
the Doctor's interest is piqued, and he offers to fund Stockwood's expedition.
But their journey proves more hazardous than any one would expected. What is the
terrible secret that pushes Stockwood on - and what is his real agenda?
Who is trying to stop their mission before it has even begun? As the Doctor begins
to piece the answers together, it seems he may be an accomplice to the terrible
tragedy that threatens to befall the island. Ancient powers are invoked, and dangerous
secrets may soon be secret no longer...
Featuring the Fourth Doctor and Leela, this adventure takes place
between the TV stories THE TALONS OF WENG-CHIANG and HORROR OF FANG ROCK.
