Can you summarize chapter 7-8

In Chapter 7, Alex is picked up outside of Felix Lester's house. Felix Lester is the real winner of the contest, but he has been sent to Florida so that Alex can take his place. The ride to Sayle Enterprises' in Port Tallon is long and boring. When they arrive, Alex is taken into Sayle's private residence where he is led to a room that is dominated by a huge aquarium. Inside is a jellyfish, a physalia physalia. Mr. Sayle tells Alex that he caught the animal while diving in the China Sea. As they chat, Alex tells Mr. Sayle to call him Alex without catching his mistake until it is too late. However, Alex is able to cover by claiming it is a nickname given him by his friends. A short time later, Mr. Sayle introduces Alex to Mr. Grin, his butler who was once a knife expert in the carnival. He had had an accident that left him with scars from mouth to ear on each side of his face. Alex is given a room on the first floor and he quickly uses the Game Boy to check for bugs, one of which he finds.

In Chapter 8, Alex finds a piece of paper stuck in the canopy of his bed. Immediately Alex recognizes his uncle's handwriting. However, the diagram and number on the paper make no sense to Alex. Alex faxes the picture to Mrs. Jones with a request for information. A short time later, Alex is taken to the Sayle Enterprise plant to play on the Stormbreaker. After playing for a time, Alex sneaks out of the room and begins searching the building. Alex comes across a stairwell that leads into a basement corridor with a locked door at the end. Alex uses a cartridge from the Game Boy to see through the door and to listen to the people on the other side. Alex hears a discussion of some sort of delivery that would take place late that night. It is then that Alex is caught by Vole, the Russian woman who is acting as his escort. Alex lies and tells her he had been searching for the toilet and had gotten lost.
