You look around but cannot see a stopcock.

'I will be two jiffies, Roy,' you say. 'I will attempt to find someone responsible for building maintenance to staunch the water.'

'Please to hurry,' comes the echoey response.

You make to the door marked PRIVATE and halt in confusion. Surely there can be no harm in disregarding the sign in this extremity? Boldly you knock and venture through.

Beyond the door you wander along several ill-swept corridors. Presently you come to a door marked JANITOR. It is ajar so you cough discreetly and enter.

Inside, you see a large hunch-backed figure lurking indistinctly in the shadows.

'Pardon me,' you say, 'are you the janitor? I have a reason for asking.'

'I am,' growls the voice, 'but I warn you that the reason had better be a good one, for I am on my lunch-break!'

'My friend is trapped in a drowning-pit. Can you turn the water off?'

By way of response, the janitor cackles loudly and holds up a huge wrench that seems too big for any maintenance work.

'No,' he says, 'but I can turn your head off!'

For the JANITOR IS A MONSTER!!!! As he shuffles out of the shadows you see he has three heads all with untreated boils on the noses. And for his lunch, he is eating a cat!!!

He puts the giant wrench on you and twists your head off!!!!!

You are killed. Now what will become of your terrapin? Really, this was a foolish choice you made. Go back and try again and this time keep your wits about you.
