it has been 20+ years since i've read them all... but i don't remember a Holmes case about a horse... Silver Blaze... yeah i looked it up but damn. i still can't remember it.

there are like more than 700 cases, mortals like us cant manage to remember them all

Detective Conan had a horse case a while ago but the setting was definitely different just being about a horse with an injured foot

conan's money... HAHAHA

Lol

either Kogoro received his monthly stipend from the 'Edogawa' family for Conan's upkeep... or the lil genius finally found Kogoro a paying gig, but he had to save Mori the Moron's ass once more. :D
