The statement of plaintiff is a lie only if the hypothesis (or antecedent) is true and
conclusion (or consequent) is not true. So the solicitor did not help his client at all. He
actually said that his client was guilty and there was no accomplice.

As there is no day when both of the beings would be lying, at least one of them must
have spoken the truth. They both speak the truth only on Sunday. However, the Lion
would then be lying in his statement, so it couldn’t be said on Sunday. So exactly one of
them lied.
If the Unicorn was honest, then it would have to be Sunday – but previously we proved
this wrong. Thus only the Lion spoke the truth when he met Alice on Thursday and
spoke with the Unicorn about Wednesday.

This conjunction is true only if both parts are true. The first part is true only on
Thursday, but the second part is a lie then (Sunday is not a lying day of the Lion). So
the whole statement is not true (at least one part is not true) and could be said only on a
lying day. Since the second part is a lie on any lying day, the Lion could have made the
statement on Monday, on Tuesday and even on Wednesday.
