Make sure that you are interested in Beasty, if not I do not believe you will get much out of it.
Read through the Change Log, use it as a road map if you are starting from the beginning, make sure you complete all scenes in Version .03 before attempting scenes in Version .04 and so on.
Read the entire Walkthrough PDF and finish it completely, then read EVERY entry in Guide by Golem98 BEFORE attempting to progress through Version .04, refer to his Guide early and often, You will need to have all the prerequisites done before Doyle will wake you and show you that you have owned a raincoat the whole time but never use it until the event you seek.
Cheers!
Or you could cheat, download the full saves that are attached to the Guide maintained by Golem98, then go into the fantasy room and replay the scene there!!!
If anything I have explained above doesn't make sense, READ THE ENTIRE THREAD, it would definitely take less time than the claimed 1000 times you have restarted the game, and ALL the answers are in there, to use your terminology at least a thousand times (exaggeration to make a point, though probably a bit less exaggerated than the restart count by a good margin)
Blunt talk from me not intended to attack or offend, just make a point
Cheers, and I do truly hope you find the Officer / Biker scene you seek, remember patience is required.
