Elementary, My Dear

is the Noble Phantasm acquired by Sherlock Holmes when materialized as a Servant. It is his Origin of "Elucidation" sublimated as a Noble Phantasm.
Even if the enigma that is being opposed is truly an unresolvable mystery, the route and the clues that will finally arrive at the truth of it will "appear" without exception. For example, even if the key to a treasure chest is lost, the key will end up "not being lost", and it appears that it can be definitely discovered somewhere in the world. (However, as one would expect, it does not suddenly appear in the middle of one's hand, and wherever it is, Holmes and his collaborators must discover it.)
Originally a continuously active-type Noble Phantasm, it has the release of its True Name performed in Fate/Grand Order. At the moment of its True Name release, an unidentifiable "sphere" appears, and it releases a dazzling light to the surrounding areas. The enemy formation is weakened and the allies formation is strengthened. Even if the opponent is supposed to be unbeatable, Holmes will find a way to defeat them.
Also, its True Name is one of the famous sayings associated with Holmes, yet the first instance in which it was attributed to him was not in 's novels, but actually in the stage play produced/scripted/starred by . It has been said that Doyle praised the Holmes played by Gillete as “surpassing the one in my novels”. Incidentally, the common assumption is that Gillete conceived it based on Holmes’ “elementary” remark towards from Doyle’s short story - “”.
