A few hours earlier, someone had told the police that thieves would try to steal the diamonds.

回答：有人向警方报告，某架飞机上有人企图偷走南非来的钻石，于是警方派员在机场守候，准备在飞机降落后严密监视，其中的一些侦探等候在主楼内，另一些侦探则守候在停机坪上。但飞机晚点了，侦探们在机场等了整整一上午。飞机到底机场后，从飞机上下来2个人，手拿装有钻石的包裹，侦探严密监视，两个侦探紧盯着舱口，另外两个侦探打开了包裹，但当他们打开包裹后，看见包裹里全是石头和沙子，而没有钻石！

大意是说尽管事前警方得知有人想偷那颗钻石，为此警方也做了精心布置，严密监视，但最终钻石还是被偷了
