The helicopter landed.Parker and Turnbull got out they were British secret service agents on an important mission. They had lots of  bags with them. 

 The helicopter had landed at p3, a military base, high up in the Welsh mountains it was a good place to hide a new weapon of mass destruction. The new weapon was called 'tiger claw' 

Agents Parker and Turnbull were met by major Stephens. He was P3's commander.

"I'm glad your here" said major Stephens "We need your help. First, you need to see the film we've made of what's going on here. I cannot watch it with you I find it too upsetting."

 The major turned away sadly. The agents could see the tears in his eyes.

Turnbull and Parker watched the film. They saw spiders crawling qround the main building of P3
