BR⑤ The long tunnel

 They waited quietly in the darkness. Suddenly a man hurried up the lane. He knocked at the window of the cottage. 'Everything is OK. Bill has telephoned from London. He's put sleeping pills in guard's coffee.' (p.20）

This book is about solution of a crime. The main character are three university student named Paul, Shelia, and Charles. In their summer vacation, they was going to stay cottage of Paul's uncle for two weeks. They was supposed to meet at the station near the cottage and Paul lead others to the place. However, at that day, Paul didn't appear there. Shelia and Charles visited the cottage with the help of map, and in the cottage there are one stranger. They got sent away by him though it must be cottage of Paul's uncle. When they hide behind grass, they come to listen to the plan of stealing money. They also heard Paul was tied up and trapped in his room. They save him and try to punish the bad guys. 

I think they are so brave and had a thrilling experience. It is good the story expand speedy, and it has happy end. When you want to read book easily, I recommend this book.
