the perferct start to a spy book

Lush green grass grew wherever grass didn't. Tall trees covered in leaves grew around the edge of the garden, like a castle wall. Roses grew in one section of the garden, daffodils and dahlias in another. Shrubs surrounded the entrance way. Poppies grew in the center garden, on top of a small hill. indeed, everything looked completely normal.

But it was a different world at night. A staff member walks into the garden every day at dusk. In the far corner of the garden there were toilets, with a key pad on the right hand side. When the staff member typed in the correct code, the gates shut.

The middle of the poppy garden was grass, with an iron edge to stop the dirt getting in the way. The staff member walks to the center of the poppy garden and, while standing in the circle of grass, stamps his foot three times. There is a creak, and the circle of grass slowly moved downwards. In fact , the gras was on an iron pole, and when that lift went down you found yourselfin a secret room in a hill on which the poppy garden was, with one staircase leading down one side.

The staircase led to 30 undergroud rooms, each different to the next. The staff member walked to the reception room. " Hows project x going?" he said.
"Almost complete" was the reply.
