沃克探长是个集邮爱好者,每年都会参加连续举行好几天的集邮者聚会,并在举行会议的旅馆三楼租了间房。这是一幢四层楼的旅馆,大楼的三四楼全是单人房间,双人房间则在二楼,因为有很多集邮迷在此过夜,旅馆特别在意客人的财产与安全问题。 Detective Walker, a philatelic enthusiast, takes part in a series of philatelists who meet for several days each year and rented rooms on the third floor of a hotel where the meeting is held. This is a four-story hotel with three or four buildings in the building, all of them single rooms and double rooms on the second floor, as there are a lot of philatelists who spend the night here, and the property pays special attention to the guests’ property and safety issues.
