Works of Sir Arthur Conan Doyle from before 1923 are in the public domain; works of Dashiell Hammett will be protected through 2041.
However, copyright in fictional characters is even more complicated than copyright in the works they inhabit. See the links below for a discussion.
Yes, both Sam Spade and Sherlock Holmes are in the public domain. The character Sam Spade was created by Dashiell Hammett in 1929, and Sherlock Holmes was created by Sir Arthur Conan Doyle in the late 19th century. This means they can be freely used by anyone without permission.
'Sherlock Holmes' was first written by Sir Arthur Conan Doyle, and then it was turned into several TV series and movies as well. [Not to mention plays, radio dramas, video games, audio recordings, etc., etc., etc.] It should be noted that Sherlock Holmes is now in the public domain. This means that anybody can write a Sherlock Homes story and need not fear a legal scolding. [Technically, the complete Sherlock Holmes will not be in the public domain until 2023 though most of it is already.] And Dr. Watson has also been very famous as he is known as the shadow of Sherlock Holmes.
Most such works are not copyrighted as they were published prior to 1923 and thus all rights have expired. Once a work has entered the public domain it cannot be "recopyrighted".
Domain Name: - It can be 67 characters long including the 4 character long top level domain (with dot Example: .com, .biz) - The characters that are permitted are letters, numbers and hypens. - The special characters that are not permitted are exclamation, underscore
Domain names can be registered in any language. Verisign offers an IDN (international domain name) converter that will convert a domain with non-English characters to Puny code or a Puny code encoded domain to native characters. See: http://mct.verisign-grs.com/
63 characters
With the exception of Plastic Man, Blackhawks, and the Spirit, all Quality Comics characters, as originally depicted, have fallen into the public domain. The new versions of those characters ("retcons") are property of their respective companies.

Yes, the story and characters are public domain. The original book was written in 1865, and anything published before 1923 is public domain. Also, the author Lewis Carroll died in 1898. Works go public 75 years after the author's death.
You can have as many characters as you want in your domain name! however, the shorter and simpler, the better. it will be easier for people to remember and get to, plus it is better for Search Engine Optimization (helping search engines, such as Google, find your website.)
The Domain Name System (DNS) has a tree structure or hierarchy, with each node on the tree being a domain name. A subdomain is a domain that is part of a larger domain, the only domain that isn't also a subdomain is the root domain.[2] For example, "mail.example.com" and "calendar.example.com" are subdomains of the "example.com" domain, which in turn is a subdomain of the "com" top-level domain (TLD). A "subdomain" expresses relative dependence, not absolute dependence: for example, wikipedia.org comprises a subdomain of the org domain, and en.wikipedia.org comprises a subdomain of the domain wikipedia.org. In theory, this subdivision can go down to 127 levels deep, and each DNS label can contain up to 63 characters, as long as the whole domain name does not exceed a total length of 255 characters. But in practice some domain registries have shorter limits than that.
The maximum length allowed for the domain name is 63 characters, the minimum length is limited to 3 characters. Please note that the maximum length applies to the coded form of the IDN (ACE-sting), the minimum length applies to the IDN itself.
The characters and basic premise are in the public domain, as is the radio show, but the television show and all materials created after 1948 are controlled by CBS.
