Neville receives a letter reporting Matthew's death in India
Date (happened)
after 1925
bound · possible
Why
No closer date is recoverable from this telling; a search on 'matthew|india|tea taster' found no other witnessing passage.
Reasoning
The only firm anchor is the 1925 London conversation. The death letter arrived only after an unspecified gap (Neville's return to New York, Matthew's departure for India, then about six more months), so the letter/death can only be bounded as sometime after 1925, not pinned to a year.
Told / reported
22 November 1971
stated · probable
Reasoning
He recounts Matthew's death from the platform in 'Gods Purpose', whose only delivery claim, read verbatim from the source document's dateline, is graded probable.
