Ans. One of the most prominent themes in The Adventure of the Three Garridebs is justice. Like most of Holmes’ cases, this one also deals with the private detective’s investigations that ultimately lead cops to the actual criminal and speeds up delivery of justice.
Another notable theme linked to the aforementioned one is the power of observation. Sherlock Holmes’ ability to solve unfathomable mysteries comes from his acute observation skills. With his objective assessment of what meets the eye, he comes up with such deductions that might seem to have been visible in plain sight all the while but others could not arrive at.
