Delhi secret tunnel sparks grisly speculation

There are few things as redolent of mystery and adventure than a secret tunnel.
So the hidden passage discovered recently beneath the colonial building that used to house the Indian parliament has prompted all kinds of exotic and grisly speculation.
The building dates from 1911, when the British moved the Indian capital from Calcutta (now Kolkata) to Delhi, and is a fine example of the architecture of the period. Walk through the grand arched doorway and you find corridors with all the hardwood panelling you would expect in a classic Edwardian expression of imperial majesty and might.
