No, no: I never guess. It is a shocking habit, — destructive to the logical faculty.

The original publication, and Doyle's manuscript (along with many other iterations across media) use "The Sign of the Four" as the title, while others (including the first book publications) use "The Sign of Four." The five-word form is used most commonly in the story, but the four-word form does show up. (More info.)
Published in novel form as The Sign of Four (1890-10).

Decisions are always made with insufficient information. If you really knew what was going on, the decision would make itself.
So we have to make guesses in order to give any utility at all to science. In order to avoid simply describing experiments that have been done, we have to propose laws beyond their observed range. There is nothing wrong with that, despite the fact that it makes science uncertain. If you thought before that science was certain — well, that is just an error on your part.

Variant: "Reality is a collective hunch."
Life is made up of a series of judgments on insufficient data, and if we waited to run down all our doubts, it would flow past us.
