High Stakes by Dick Francis for DOS based on the Book. Steven Scott, all-around success, a toymaker of considerable ingenuity, and a race horse owner on the side, hasn't noticed that he's been stolen blind by his trainer and a bookmaker until a brutal assault, which, along with alcohol dripped into his veins, leaves him doubly knocked out. Then there's the theft of his best horse Energise who will be run under a different name. No personal problems this time (Francis readers usually enjoy them)--just a straight run somewhere in the middle of the form which is authoritatively and exclusively his, hers and theirs.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
