A murder will occur this weekend in the peaceful seaside tow

A murder will occur this weekend in the peaceful seaside town of Langley, Washington. In fact, a murder has occurred there every February for the past 25 years. But don’t panic! It’s all part of the town’s yearly Mystery Weekend.
What began as a local event in 1984 now attracts visitors from over the U.S. and even abroad. Would-be detectives（侦探）arrive on Saturday. There, they receive a packet, including a newspaper with details about the crime and information telling where to find clues（线索）. Visitors then travel to various shops, restaurants and other places, searching for clues as they go. Along the way, they meet and interview suspects (疑犯) played by local people. The visitors need turn in their guesses on Sunday at 4:00 p.m.. Then as everyone gathers, the murderer is found, and prizes are awarded for correct answers.
For visitors, Mystery Weekend is not only fun but also a great introduction to the charms of Langley. It’s a very attractive place with historic buildings, exciting ocean views and above all, friendly people. Since Langley is on an island, a fun way to get there is by taking a ship to the nearby town of Clinton and then driving the rest of the way. Langley has a delightful selection of hotels with bed and breakfasts that are open all year round. And activities in Langley aren’t limited to Mystery Weekend. There is also great hiking, biking, golfing and diving to enjoy. And for a special adventure, visitors can book on one of the whale–watching ships that leave nearby harbors each day.
