The program on Richard's radio when he has a bowl of soup at 9 p.m. is "The Lone Ranger" which aired at 7:30 p.m. Eastern time, not 9:00 p.m.
Velie tells Ellery that there's been a murder in Bayside, but later, a newscaster refers to the scene of the crime as being in the Bronx. Bayside is a neighborhood in Queens County (just west of Douglaston, which Ellery visited earlier in the series in The Adventure of the Mad Tea Party).
