I think this position is misprinted, the correct place of
the white king might be: Kh8.

Btw., the book also contains some problems, where the retroanalytic
content is intended, like:

No. 1942
W: Kg8 Rb7 Rc7 
B: Ra8 Ke8 Pg7 Ph6 

fen= r3k1K1/1RR3p1/7p/8/8/8/8/

or

No. 1747
W: Pb2 Pc2 Qc1 Ke1 Rh1 
B: Ka2 Nb1 

fen = 8/8/8/8/8/8/kPP5/1nQ1K2R

Most interesting for me was

No. 1513 (and similiar No. 1517)

W: Nb8 Kc8 Rb7 Pa6 
B: Ka8 Ra7 

fen = kNK5/rR6/P7/8/8/8/8

According to the book, the composer of this problem is
Mrs. W.J.Baird, 1907.

Is it really likely that Mrs. W.J. "Twentieth Century Retractor" Baird
overlooked such a simple retroanalytical fact?
