Irene doesn’t know the password for the USB drive, so it seems like she and Sherlock will part ways for a time…only for her to end up at Bar Pipecat, ordering the other detectives to do chores and maintenance while Mrs. Hudson is laid up with a bad back (or as she calls it, “that time of the month”). When a new client comes in whose ex is trying to gain custody of their young daughter through blackmail, Irene decides to take the case, picking Watson as her partner.
When the girl’s mother suffers a fainting spell, Sherlock is left to babysit her, and while things start out rough at first (rice bowl with fried egg and a chocolate bar? NO GO) the two come to a sort of truce. Meanwhile Irene proves an astute investigator and gatherer of information, making more progress than all the other detectives and locating the blackmailer ex’s home, at the night swimming pool right next to the district’s famous Elephant.
Turns out the guy is a serial blackmailer, manipulator, and trafficker of underage women—a super bad dude. A woman Irene used to co-star with, who is also being blackmailed, ends up giving Irene the clue she needs to find the safe containing all of the compromising information, including the client’s.
At this point Sherlock joins the investigation (his rakugo is quickly dismissed by Irene as too slow), and the two end up sharing a tanning bed as a hiding spot, only for the blackmailer to be murdered by the actress in a crime of passion. Irene lets her get away, since she’s suffered enough, but when she returns to her hotel room, Irene finds the actress’s ear in a box. Jack the Ripper has apparently made Irene his next target.
