This is The Treasure Of Alpheus T. Winterborn by John Bellairs. Stupidly, this was aired as "The Clue According To Sherlock Holmes" in 1980. Ignore the stupid Sherlock Holmes stuff lol.
Anthony Monday - Keith Mitchell - changed his name to Keith Coogan in 1986.
Miss Ells - Dody Goodman
Mr. Loomis - Louis Guss
Mrs. Monday - Claire Malis
Mr. Monday - Stanley Grover
Hugo Philpotts - Matthew Tobin
The strange man in the Library and we later find out he's a Fireman is played by Frank Dent. I had to do alot of searching online to find out that one!
Al Lewis who played Grandpa Munster from The Munsters plays the auctioneer Mr. Gegenfurtner.
There are two names that I can't find out what characters they are in the show - Art Kassul & Hale Porter.
I love John Bellairs!!!
