In the long run I need to improve my memory, somehow. Or else I could stick to reading こころ and 博士が愛した数式. In the short term, I sometimes replace the bookmark that Japanese publishers kindly provide with a piece of paper on which I can note down the names of the characters as they appear. That works quite well. Actually perhaps the act of writing them down helps them stick in the memory, as I find that quite quickly I don't need to refer to the bookmark unless the character hasn't appeared for a hundred pages or so. If you're learning to read like me, I strongly recommend it.
That said, if you're going to read りら荘事件 (The Villa Lilac Case) by 鮎川哲也 (AYUKAWA Tetsuya), perhaps my notes can save you some time.

To be honest, I didn't find it a very enjoyable book. It's an attempt at a thoroughly classical puzzle mystery, first published from 1956-7 and then in book form in 1958. A group of students gather for a break at a villa belonging to their university in the hills north west of Tokyo. One by one they and those around them get killed, until the police are left with hardly any suspects to choose from. It's a carefully plotted mystery, with a lot of tricks and clues. But I think it has some terrible problems.
Firstly, the murderer is much too obvious. Before I was a quarter of the way in I had a rough idea of who the killer was and what was going on. That was less than a hundred pages in, and it's a long book (about 400 pages), so that I had another 300 pages to go. At the end more or less everything I'd worked out or guessed turned out to be right. All this time the police are shown as bumbling incompetents, neglecting the most obvious questions and evidence. The experience is like having to watch someone else play a computer game badly for hour after hour. The real detective is not even mentioned till the last fifth of the book; and we have to read on quite a few pages before he makes an actual appearance. There's the same structure, and the same problems, in a 島田荘司 (SHIMADA Souji) book that I read recently, 斜め屋敷の犯罪 (The Crime of the Slanted Country House), a locked room mystery from 1982, which seems a deliberate attempt to emulate traditional mysteries like りら荘事件. In that case too, the culprit is very obvious; but I at least did not have the solution to the central puzzle (though certain elements of it are obvious, too).
Coming back to Ayukawa's book, the characters were a problem for me too. They are none of them interesting and most are fairly unlikable. A writer has no duty to cater to a taste for likeable characters of course. If you've always wondered, 'What's it like to spend a couple of weeks with dull, unpleasant, quarrelsome people?', you may find it enlightening.
But perhaps my level of Japanese is a problem here. It took me over two weeks to get through this. If it was in English, I would have read it in a couple of days and looked more tolerantly on the characters and the puzzle. You can read another blogger's more positive take on the book here.
