Philo Gubb by Ellis Parker Butler

It would not be true to say that Mr. Gubb had become suspicious of Mr. Medderbrook's honesty. The fact that the cashier of the Riverbank National Bank told him the Utterly Hopeless Gold-Mine stock was not worth the paper it was printed on did pain him, however.

It pained Mr. Gubb to think his father-in-law-to-be might be guilty of even unconscious duplicity, and when Mr. Master paid him the six thousand and seventy-five dollars Mr. Gubb decided that only three thousand dollars of it should pass immediately into Mr. Medderbrook's hands. Mr. Gubb put two thousand dollars in the bank and invested the balance in furniture for his office and in articles and instruments that were needed for his detective career. The three thousand dollars he took to Mr. Medderbrook and paid it to him, leaving only eight thousand nine hundred dollars unpaid.
