There is a small building

Built from Bath Stone

Not far from Avoncliff in Wiltshire

The pale building is positioned on a quiet road

And faces the railway

It was built in 1943

At the request of the Water Board

But is now quite overgrown

Two years ago Dan Chaucer and Elena Undressing

Visited the building

And reported that it was in good condition

After some difficulty

They gained entry to the building

And found it to be full

Of Swiss Army Knives

The knives had been abandoned

By the retreating forces

In the final months of 1944

Both Dan Chaucer and Elena Undressing

Have written books on the subject

But the actual location of the building

Has not been revealed before
