How does Homeward Path work with cards that enchant to steal?
Even though Homeward Path looks to have an instantaneous effect, it's actually continuous:


  611.1. A continuous effect modifies characteristics of objects, modifies control of objects, or affects players or the rules of the game, for a fixed or indefinite period.


Since both continuous effects apply in layer 2:


  613.1b Layer 2: Control-changing effects are applied.


you have to apply them in timestamp order:


  613.2. Within layers 1–6, apply effects from characteristic-defining abilities first (see rule 604.3), then all other effects in timestamp order (see rule 613.6). Note that dependency may alter the order in which effects are applied within a layer. (See rule 613.7.)


If Homeward Path is activated after In Bolas's Clutches is cast, the owner will get the creature back:


  613.6. Within a layer or sublayer, determining which order effects are applied in is usually done using a timestamp system. An effect with an earlier timestamp is applied before an effect with a later timestamp.
