Hot Seat ~ Pt. 2

Warren, sitting stone-faced, looks at the man who got him into the detective branch and wonders what or how much can be told. Sugden was not an unreasonable man, but he has limitations and time travel surely would be one.
Giving only bare details, of the past two weeks, Warren explains his undercover idea and the lead regarding the fight between the 'drunk' (Jack) and Mr. Ó Seachnasaigh; he further explains his trip to the hospital to visit the injured man.
OK, Warren, I see where your going with the Petticoat Lane leads and that is good ground work, although you don't seem to have turned up anything concrete.  You need to interrogate the prisoner and see what you can find out about him. Assume he has information that is related to the case and push him to talk. Seems doubtful, given he is a drunk and probably unreliable, but maybe that is a rouge.
Before Warren can steer his boss away from that thought, Superintendent Sugden asks again about the hospital lists. Well, sir, if the chatter is to be believed, then it's possible our murderer is a doctor or nurse at The London Hospital. Don't forget, Dr. Openshaw, who examined the package containing part of a kidney, is practicing there. Also, the case for patients is still an option since there hasn't been an attack for several weeks; he could have taken ill or been in a fight, like Mr. Ó Seachnasaigh and gotten severely injured.
Yes, yes, I see where you're going with this as well...good thinking detective. Sugden finally smiles. He wasn't wrong to push Warren's promotion after all. I'm glad to have you on the case, but you need to keep me abreast of what you're doing and any progress --- positive or negative. Do you understand me?
Yes sir, you've made it clear. Good. Now head over to the Whitechapel Station and see what you can do with our drunk. Right away sir!
Warren leaves Sugden's office smiling. Whoa! That was a very near escape. Wiping the sweat off his brow, Warren makes his way through The Yard. Running into Constable Crane, an eager new policeman with his eye on becoming a detective himself. Calling after Warren, Sir, Inspector Warren... Yes, Crane, what is it? Excuse me sir, but a package came for you about an hour ago, while you were in the Super's office; the courier said it was urgent. Oh? Yes, I left it on your desk; I just grabbed it for you, since I saw you passing by. Constable Crane hands the parcel to Warren. I noticed there wasn't a complete return address; just a name. Looking down to read the label, Warren feels himself go pale. Not wishing to fuel the young policeman's curiosity any further, he quickly thanks him and dashes out the door.
Unknown to Warren and Crane, the contents of the parcel mean life or death for Jack.
