You are a mafia leader and because of mysterious recent developments, you had to call the meeting of heads which is happening right now at your's cousin restaurant. The problem is, after the opening toast, Urlich the Unusual who was the key person today fell dead from poison in his glass. It's your turf and to avoid bad name and escalation you have to find who did it.
There are four immediate suspects:
- Sam the Sommelier, who poured the wine
- Tom the Trickster, who sat to the left of Urlich
- Violetta the Violent, who sat to the right of Urlich
- Willy the Waiter, who served the food to Urlich
Certainly all of them will try to avoid getting on your bad side, yet, they also want to appear defiant in the eyes of the others. In other words, at least one claim about another person is true and at least one will be false. This is what they say:
Sam the Sommelier:
Tom did not do anything. And neither Miss Violetta. It was that damn waiter, it is his fault.
Tom the Trickster (replying to Sam):
Yeah, of course, you're just angry at the kid, it was you, you sneaky, tasteless murderer. Me, Viola, sure are innocent. But Willy, come on, he's 15 or 16 or whatever, he didn't kill anybody!
Violetta the Violent (replying to Tom):
\$#%@ Of course he #@\$# didn't! Because it's you ^@#\$@#$, who is true culprit, you %%^@#\$! Leave the %#% staff alone %#\$@#\$, Sam's alright, I'm #\$% certain he's innocent, you %^@#%!
Willy the Waiter (to the narrator, the mafia leader):
I'm sorry sir I didn't react in time, I saw it, I should have told you, it was the lady over there, she put the poison in the glass. Sam is innocent. The gentlemen at the table is innocent too, I'm sorry sir, please don't kill me!
As for yourself, you know that it was not a suicide, and from everyone present only the four suspects could have done it (in particular it could not have been you, the mafia leader). All had reasons not to, but nevertheless, Urlich was murdered. Of course, Sam would whine about Willy, because since the kid was hired, the tips had to be split even more. Naurally, due to his nature, Tom would defend the boy and blame Sam in turn. However, one thing bugged you: you know that Sam and V. detest each other so much that it would be impossible for them complete a single task together, and yet, she still had defended him. This doesn't sound right. What is going on? Who is the culprit?
Additional clarifications (because comments might be missed):
- the narrator did not do it,
- it is possible that the crime was done by more than one person.
