One good trick for Christies is that she loves to have simple motives at the end of the day; a husband wants his wife out his way so he can remarry, a simple trick to come into some money. Often a character will be suspicious since they obviously benefit from the crime, but due to the particular mechanics or circumstances it seems like it can’t be them. The core to the solution then ends up being the explanation of how it was physically possible for them to do it.

Another good trick- >!never trust people who apparently hate each other! Christie loves to reveal that a pair of perfect enemies are in fact putting up a front, disguising the fact that they’re co-conspirators!<
