here) is that it is in a "bedroom community" where neighbors can be avoided; very suitable for a Time Patrol agent, like Everard's New York apartment.
Everard does not need to know where or when Shalten is from. The latter, though not Jewish, wears a skullcap. In Robert Heinlein's Future History, men wear kilts. The only point here is that the future will be different. Heinlein is often in the background of Anderson's futuristic fiction. We compared Laurinda Ashcroft with DD Harriman here and Three Worlds To Conquer with Farmer In The Sky here.
Shalten seems to take what he likes from the ages that he visits, importing souvenirs from 1902 to 1987, drinking tea with Amaretto and Triple Sec and smoking perfumed tobacco in a churchwarden.
He thinks carefully about where and when the Exaltationist time criminals might go and how a trap might be laid for them in one of these places or times. Don't believe everything that you read in the newspapers.
