Hey! I have a copy of “The Complete Sherlock Holmes Collection”, part of the Barnes & Nobles Leatherbound Classics. It is a 1000+ pages, and from what I can tell it has the whole collection, 56 short stories and 4 novels. The pages also have this absolutely beautiful gold/brass lining that gives it this antique/vintage look. I love it, it’s one of the favourite pieces in my collection. However I bought mine a couple of years back so not sure how easy it is to find right now, but I think it may be worth the search! Here’s the link for Amazon UK: The Complete Sherlock Holmes (Barnes & Noble Leatherbound Classic Collection): Barnes & Noble Leatherbound Classics https://www.amazon.co.uk/dp/1435167902/ref=cm_sw_r_cp_api_i_nIZKFbZHJSK2K.
Sabes inglés? En ese caso, te recomiendo mucho "The Complete Sherlock Holmes", que incluye todas las historias y novelas en las que aparece el personaje, en orden cronológico.
Si no, te recomiendo que compres las colecciones de historias cortas (a mi parecer, son mejores que las novelas). Creo que Editorial Porrua las tiene como "Aventuras de Sherlock Holmes". La única novela que te falta, realmente, de las "esenciales" es "Estudio en Escarlata"; que cuenta la historia de cómo se conocieron Holmes y Watson.
Yes, this has all 4 novels that Conan Doyle wrote as well as the 56 short stories. Here’s the link: https://www.amazon.com/Complete-Sherlock-Holmes-ARTHUR-author/dp/1435167902
Happy reading :)
