In mystery novels, a common theme is the presence of a mysterious or suspicious character. This character might be the villain or just someone with a hidden agenda. Another theme is the setting which can add to the mystery. For example, a spooky old mansion or a fog - covered alley can enhance the sense of mystery. Additionally, the theme of danger is often there. The characters, especially the protagonist, are usually in some kind of danger as they dig deeper into the mystery. It could be physical danger like being attacked or more of a social danger like having their reputation ruined.
One common theme is the search for truth. The detective or protagonist is constantly trying to figure out what really happened, whether it's a murder, a disappearance, or some other mystery. Another theme is deception. There are often characters who are lying or hiding something, which adds to the mystery. Also, justice is a big theme. Usually, the mystery is solved to bring about some form of justice, whether it's putting a criminal behind bars or clearing an innocent person's name.
Redemption is another. Often, the mystery is intertwined with a character's journey towards redemption. They might be searching for answers to past wrongs or trying to make amends, and the mystery they are solving helps them in this spiritual journey. This can be seen in novels where a character is trying to figure out a long - lost family secret that also has a connection to their spiritual growth.
One common theme is the search for truth. Detectives or protagonists are often on a quest to figure out what really happened in a crime or mystery situation. Another is the idea of justice. They strive to ensure that the guilty are punished. Also, there's often an element of the unknown, like strange settings such as old haunted mansions or fog - covered alleys which add to the mystery.
A major theme is the battle between good and evil. The doctor in the mystery novels usually represents the good side, trying to expose the wrongdoings or solve the mystery caused by the evil side. Also, the theme of redemption can be seen sometimes. Maybe a character has made a mistake in the past and through the process of solving the mystery, they seek redemption. In 'House of Silk', the detective is not only solving the mystery but also dealing with his own moral compass and the idea of redemption in a way. And another common theme is the power of the mind. Doctors in these novels often rely on their mental faculties to solve the mystery, whether it's through psychological analysis or pure deductive reasoning.

In castle mystery novels, the theme of the past coming back to haunt the present is quite common. The long history of a castle can hold many untold stories that resurface in mysterious ways. The mystery of inheritance is also there. Who gets the castle and its treasures? This is often a central question in many such novels. And there is always the sense of an unknown danger lurking within the castle's nooks and crannies, which keeps the readers on the edge of their seats.
The theme of the femme fatale is quite common. A beautiful and mysterious woman may be involved, either as a victim or as the murderer herself. Another is the theme of the haunted past. The murderer's actions could be rooted in some traumatic event from their past. Also, the theme of the hidden identity is often seen. A character may not be who they seem, and this is closely related to the mystery of the murder.
Another theme is the exploration of human greed. The valuable objects or inheritances that are often at the center of the murders in these novels, such as in 'Murder on the Orient Express' where the motive seems to be related to a past crime and the money involved. People are willing to kill for wealth or power.
One of the most common themes is the search for truth. The detective or the main character is often on a quest to uncover what really happened in a crime or a mysterious event. For example, in Sherlock Holmes stories, Holmes is always deducing facts to get to the bottom of the mystery.

But in gay mystery novels, these relationships are within the context of same - sex attraction.
