the seven sleuths

Well, Miss Marple from Agatha Christie's novels could be considered a spinster. She's an unmarried woman who's highly skilled at solving mysteries.

Often as brave and resourceful. They have to be, as they're usually up against some tough odds. For instance, in many YA mystery novels, the sleuth might be a teenager in a small town where strange things are happening. They're not afraid to go into old, creepy houses or question suspicious characters.

Well, Sherlock Holmes has a sister in some fictional works, Enola Holmes, who is a very clever female sleuth. She uses her wits and skills to solve various mysteries. Also, Phryne Fisher is a popular female detective. She's glamorous and fearless, often getting involved in complex cases in the 1920s - era settings. There's also Kinsey Millhone, a private investigator known for her determination in solving cases.

Their intuition often sets them apart. Female sleuths tend to rely on their gut feelings more than male counterparts in some stories. For example, Miss Marple often just 'knows' something is off based on her life experiences and her understanding of human nature.

Female sleuths often have great intuition. For example, like Precious Ramotswe in 'The No. 1 Ladies' Detective Agency', she can sense things that others might miss just based on her life experiences and her natural perceptiveness. They are also usually very determined. Take Kinsey Millhone from 'A is for Alibi', she won't give up on a case easily no matter how difficult it seems.
