根据字母统计得出：
L=149次，
G=120次，
V=105次，
K=87次。
猜测L是e的加密，G是t的加密；e和t对应的数值是4和19，L和G对应的数值是11和6。
对于仿射密码，有c=(k_1m+k_2).
得出以下方程组：
11=(k_14+k_2)
6=(k_1*19+k_2)
这个方程有唯一解：k_1=17 ，k_2=21；gcd(17,26)=1;
密钥K=(17,21)。
解密得出：
Now, though, that meadow scene is the first thing that comes back to me. The smell of the grass, the faint chill of the wind, the line of the hills, the barking of a dog: these are the first things, and they come with absolute clarity. I feel as if I can reach out and trace them with a fingertip. And yet, as clear as the scene may be, no one is in it. No one. Naoko is not there, and neither am I. Where could we have disappeared to? How could such a thing have happened? Everything that seemed so important back then - Naoko, and the self I was then, and the world I had then: where could they have all gone? It's true, I can't even bring back her face - not straight away, at least. All I'm left holding is a background, pure scenery, with no people at the front. True, given time enough, I can remember her face. I start joining images - her tiny, cold hand; her straight, black hair so smooth and cool to the touch; a soft, rounded earlobe and the microscopic mole just beneath it; the camel-hair coat she wore in the winter; her habit of looking straight into my eyes when asking a question; the slight trembling that would come to her voice now and then (as though she were speaking on a windy hilltop) - and suddenly her face is there, always in profile at first, because Naoko and I wer e always out walking together, side by side. Then she turns to me and smiles, and tilts her head just a little, and begins to speak, and she looks into my eyes as if trying to catch the image of a minnow that has darted cross the pool of a limpid spring.
译文：
不过，现在我首先想到的是草地上的景色。草的味道，风的微弱寒意，山峦的线条，狗的吠叫：这些都是第一件事，而且都是绝对清晰的。我觉得我好像可以伸出手来用指尖追踪他们。然而，尽管场景可能很清晰，但里面没有人。没有人。直子不在，我也不在。我们可以消失在哪里？怎么会发生这样的事？所有在当时看来如此重要的东西——直子，我当时的自我，我当时的世界：他们都去了哪里？是真的，我甚至不能把她的脸带回来-至少不能马上带回来。我只剩下一个背景，纯风景，没有人在前面。是的，只要有足够的时间，我就能记得她的脸。我开始加入到画面中——她那纤细冰冷的手；她那笔直的黑发，摸起来如此光滑凉爽；柔软圆润的耳垂和耳垂下的微小痣；她冬天穿的驼毛大衣；她问问题时直视我眼睛的习惯；她的声音时不时会有轻微的颤抖（仿佛她在一个有风的山顶上说话），突然她的脸出现了，一开始总是侧面的，因为直子和我总是在外面肩并肩地走着。然后她转向我，微笑着，把头稍稍歪了一下，开始说话，她看着我的眼睛，好像想抓住一条小鱼的形象，它已经飞过清澈的泉水池。
