1 Answer 1


The murderer is

Hyman Yarn


if you move the $n$th letter in "Hyman Yarn" ahead by $n$ places in the alphabet (wrapping round from Z to A if necessary), you get "Iapes Ehzn". At least, this works for all but the last letter - possibly the OP made a mistake with that one?


H -> I
Y -> Z -> A
M -> N,O -> P
A -> B,C,D -> E
N -> O,P,Q,R -> S
Y -> Z,A,B,C,D -> E
A -> B,C,D,E,F,G -> H
R -> S,T,U,V,W,X,Y -> Z
N -> N (?)

Thanks to mr23ceec, "Ictlb Puod" also fits the same person because

if you move the $n$th letter in "Hyman Yarn" ahead by $3n-2$ places in the alphabet, you get "Ictlb Puod", with some letters out by exactly one place (maybe the OP miscounted?) and again the last letter not quite working.


H -> I
Y -> Z,A,B -> C
M -> N,O,P,Q,R,S -> T
A -> B,C,D,E,F,G,H,I,J -> K L
N -> O,P,Q,R,S,T,U,V,W,X,Y,Z -> A B
Y -> Z,A,B,C,D,E,F,G,H,I,J,K,L,M,N -> O P
A -> B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S -> T U
R -> S,T,U,V,W,X,Y,Z,A,B,C,D,E,F,G,H,I,J,K,L,M -> N O
N -> D?

  • $\begingroup$ That's what I got for Ictlb Puod but threw it out coz it didn't quite work out. There's sort of a pattern. $\endgroup$
