Anachronism

 A subset of literature that I occasionally dip my toe into is "Sherlock Holmes" 'extended' fiction. This is essentially where the character of Sherlock Holmes is inserted into another setting, as a kind of writers device to tie a story about a different topic together. 

In chess the most famous example is "The Chess Mysteries of Sherlock Holmes" by Raymond Smullyan. This is in fact a book about retrograde analysis in chess, but presented as using Holmes as a way to make it more readable. 

I found a similar book set in the world of Contract Bridge, "Sherlock Holmes, Bridge Detective". Again it is a series of problems, woven together by a narrative involving the fictional detective (and Dr Watson), as participants in a challenge match. In this case, all well and good, except for the fact that the suggested date of Holmes' passing was March 1927, and Contract bridge (as used in the book) did not become established until 1929.

Nit-picking for sure, but also the sign of laziness on the part of the author,
