Mr. Hall Pycroft got left without a job after the company he worked for closed down. When Pycroft finally found a new workplace at Mawson & William's firm, he got suddenly offered yet another position in the Franco-Midland Hardware Company. Pycroft was going to receive three times higher salary if he accepted to work for the latter. However he was not to hand his resignation to "Mawson & William". Something did not quite add-up and Pycroft's suspicion started growing bigger. He reached out to Holmes and asked him to check up on the two brothers, Franco and Midland.
