A Clue in Code by Marilyn Singer, 1985.
This book is part of a series about a pair of twin boys, Sam and Dave Bean, who solve mysteries with their friends.
One day, the boys’ teacher, Ms. Corfein, has one of their classmates, Roger, collect money from the students for a class field trip. Ms. Corfien tells Roger to put the money in her locker, but later, the money is gone.
Anyone in the class could have taken it. When Dave went into the classroom to feed the class’s pet gerbil at lunchtime, he saw Willie, the class bully, there as well as his friend Patti, who thought that it was her turn to feed the gerbil. Of the two, Willie seems like the best suspect for the theft because he’s been in trouble before for stealing, but perhaps there was someone else in the room before any of them arrived.
Sam and Dave decide to begin their investigation with Willie. His father is the school’s custodian, and Willie has been using a copy of his father’s key to the school to sneak around after hours. To the twins’ surprise, when they confront Willie, not only does Willie deny stealing the money, but it turns out that he’s actually been scared and upset himself. After being caught stealing the last time, his parents have been especially strict with him, sending him to bed early, limiting his time with friends, and not allowing him to watch tv or read comic books. In fact, his father tried to get rid of his entire collection of comic books by throwing them in the trash, but Willie rescued them and has been hiding them in the school, sneaking away to read them when he can. However, someone has discovered them and stolen them. Willie wants his comic books back, but he can’t report them stolen because his father thinks that they’re already gone. Worse still, his parents will be even harder on him if he ends up taking the blame for stealing the class’s trip money.
In spite of Willie’s reputation, which he deserves, Sam and Dave think that he’s telling the truth about the thefts. Then, they happen to find a strange message that appears to be written in code after some of their classmates were throwing paper airplanes. With the help of Rita, a friend who is very good with codes, they decode the message and uncover a valuable clue that explains why the comic books were taken and leads them to the thief’s identity.
I was pretty sure, from the very first chapter, who had stolen the money, but I wasn’t completely sure of who had taken the comic books until the end. At first, I thought perhaps Willie’s father had found his stash and got rid of it again, but that wasn’t the case. The thief who took the comic books was the same person who took the trip money and for the same reason. This person’s father has been out of work, and they need the money. It turns out that Willie has a number of comic books that are now collectors’ items, and someone is willing to pay a lot of money for them.
Top Secret by John Reynolds Gardiner, 1984.
Allen is angry that Miss Green didn’t take him seriously, and lipstick is the last thing that he’s interested in. His parents think that he should just do the lipstick project and forget about it. Even if human photosynthesis were possible, how could a nine-year-old possibly achieve such a thing? Real discoveries are made by important men, not little boys. However, Allen’s grandfather encourages him to persevere in what he wants. He says that Allen has everything that a important man would have: five good senses and a brain that he can use to think. Allen’s grandfather often thinks about strange things himself, and he encourages Allen to think all the time.
Although Allen acts like he’s carrying out the lipstick project, with his parents’ help, he continues studying photosynthesis on the side. When Allen gets stuck on what to do next, his grandfather advises him to “think crazy,” to just let his mind explore possibilities and see what it comes up with.
The Plant That Ate Dirty Socks by Nancy McArthur, 1988.

General Butterfingers by John Reynolds Gardiner, 1986.
Mrs. Wilson and Walter talk to a lawyer, but he says that, since the General apparently didn’t leave a will, the estate has to go to his nearest relative, which is Ralph. As far as he’s concerned, there’s nothing they can do about, even though the General made a verbal promise to the men that they could stay in his house for the rest of their lives.
In some ways, you could feel sorry for Ralph, who is a very unhappy person. Because of his meanness and selfishness, his father spent years giving him pretty much anything that he wanted on the condition that he not come around to see him. Ralph is hurt at his family’s avoidance and disdain for him, which is why Walter, at one point, invites him to come for dinner and be their friend. However, Ralph’s motives are always selfish, and that causes him to suspect that the same is true of everyone, so he refuses their kindness. It gives the impression that he’s probably done the same for many others over the years, for the same reasons.
