格雷森先生是一位成功的商人,他的公司制造工厂用的机器和工具。这些机器和工具很受厂主们的欢迎,销售得很好。最近他发现他的竞争对手对他的销售计划了如指掌(in detail)抢走了他的客户。无论他的推销员到哪里去,总是晚了一步。对手的推销员早已到达,而且报价总要低一些。这种泄密的情况使格雷森先生损失了上百万美元。于是他请来了被称为“思维机器”的侦探,来调查情报是如何从他的办公室泄露出去的。这位侦探问了商人一些问题之后,他就断定是商人的私人秘书把他的计划给出卖了。次日他在她桌子上的一个银匣子里找到了证据(proof)——— 一个电话联线装置。 Mr. Grayson was a successful businessman, his company made machines and tools used in factories. These machines and tools were truly liked by the factory owners and sold well. Recently, he found that his competitors knew his sales plan in detail and stole his customers.

This information leak cost Mr. Grayson millions of dollars. So he invited a detective known as The Thinking Machine to find out how the information leaked from his office. After the detective asked the businessman some questions, he decided that the businessman's personal secretary had sold his plan. The next day, he found the proof in a silver box on her desk ——— a telephone connection.
