I like it, brimfin. Let’s see… Albert knows her birth month, Bernard knows her birth day, and neither knows her “birthday,” which here means both pieces of information, month and day. A knows that B does not know the birthday, just the day of birth. In that case, it must be one of the days that repeat, as A knows that B only knows the day—but it has to a day that is not unique, as he doesn’t know the birthday. Otherwise, if C had told B, “18th” or “19th,” he would have known the month had to be June or May, respectively. As A knows that B doesn’t know it, and doesn’t know it himself, it must be a month with a repeating day—July or August. Otherwise, if it had been May or June, A wouldn’t “know for sure” that B didn’t know it, as B could have gotten the 18th or 19th, which would point directly to a month (and to B’s knowing).
That leaves our options as Jul. 14, Jul. 16, Aug 14, Aug. 15, or Aug. 17. However, B now knows the answer just by knowing the day—which means that it can’t be the 14ths, or he’d not know it for certain because there are two. So we have Jul. 16, Aug. 15, and Aug. 17. I was stuck here for a long time and am still not completely sure if my answer is correct. OK, then: A, who knows the month, knows the birthday (month+day) because B, who knows the day, knows the birthday. If either of the August dates were the answer, though, A couldn’t know for sure; he only knows the month, and knowing that it was August wouldn’t give him the day as well. So it must be Jul. 16, as he knows the month must be July, and it’s the only choice left in July.
Now I’m sure I made a mistake somewhere—I also do with these. Yes, you made one mistake - in thinking that you made a mistake in your solution. You did not. Your answer is 100% correct. Great job. 😁

This is real easy, but here ya go, folks…
Tim Chivet, a famed restaurant critic and man-about-town, has been murdered. You are a police inspector. Which of the following suspects committed the very foul deed?
1. Ned R. Hirger—an erstwhile apocalyptic preacher, now a used-car salesman. Was seen with a lead pipe in one hand and a wrench in the other—you suspect he was being blackmailed by Chivet.
2. Manny Torou—an Andorran chef, very skilled with a knife and with a revolver. Hated Chivet because the man wrote a nasty review of Torou’s new restaurant.
3. Renié Thother—a gorgeous French model with more curves than Lombard Street. Equally accomplished with a dagger or with poison and was having an affair with Chivet at the time of his death.
4. Elli Kerth—Chivet’s fiancée, who just found out about Mlle. Thother. Knows a great deal about firearms and ropes.
5. Sir Roger A. Hendal—Chivet’s uncle, a blustery old barrister who insists on impersonating Horace Rumpole. Hated the wasteful Chivet. Last seen threateningly brandishing a candlestick.

Salzmank, I got excited when you said this was "real easy" but 24 hours later I still can't figured it out. Just wondering: Does the fact that all of the weapons mentioned are from the board game Clue have any relevance?

Hey, happy to see you back here, jervistetch! I suppose it’s one of those “real easy once you get the trick” kind of puzzles, if you know what I mean. As for your question… No, I mostly intended it as a gag. I should note that this isn’t an exercise in deductive or inductive logic (or any kind of logic, in fact)—it’s more riddle-ish, more with a single trick (if that makes sense).

One more thing. (As Columbo would say.) How do you tag another board member? I can NOT figure that out.

No worries, jervistetch… You put the @ symbol in front of the member’s user name, but it has to be the name in black under the picture. For you and me, it’s the same as the username in blue over the picture—salzmank and jervistetch. For some people, it’s different—alowarks and alfromni, for example. So I take the name in black, put the @ symbol in front (no space), and you tag someone!

NalkarjTim Chivet murder: Would I be wrong in thinking this is some sort of play on the names of the suspects? --------- sandgrownunNothing in your post.

Correct indeed, alfromni . P.S. sandgrownun PMed his answer to me. He’s right about who the killer is, but there are a few more complications.

Nalkarj - Tim Chivet murder I think the answer is... Elli Kerth. An anagram of "the killer".

Nalkarj 1. Ned R. Hirger - H(enry) Derringer
Are they all to do with weaponry?

alfromni No… Different anagram for Hirger, and different kind of theme.

Nalkarj --- OK, Is my "Hirger" incorrect?
