Some questions without answers.

     I have made myself a list of the things, that needed explanation Here it is:

1. Who is the owner of the handkerchief with the initial H.? - being pressured, Princess Dragomiroff admitted, that the handkerchief belonged to her
2. Was the pipe-cleaner dropped by Colonel Arbuthnot, or by someone else?
3. Who wore the scarlet kimono?
4. Who wore the Wagon Lit conductor's uniform? - It is certainly someone from the outside
5. Why do the hands of the watch point to 1:15?
6. Was the murder committed at that time? - certainly not
7. Was it later?
8. Was it earlier?
9. Can we be sure that the victim was stabbed by more than one person? - It seems most logical, yes
10. What could be the other explanation of the wounds?

     Some questions were answered, some were not. The only thing we can do about it is think. We might come up with an idea, or deduct something by analysing the psychology of the suspects.

Let us all three close our eyes and think...
