Sir Arthur Conan Doyle 
Firm of Girdlestone 

Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a Scottish writer and physician, most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction. "The Firm of Girdlestone" is a novel by British author Sir Arthur Conan Doyle. John Girdlestone owns the firm of Girdlestone. It is a very lucrative business and John Girdlestone and his son Ezra Girdlestone are respected by everyone. Both father and son are cynics and have no other thought but for their business; after giving a donation of GBP25 for charity, John Girdlestone remarks to himself that it is not a bad "investment", as it will make a favorable impression on the collector, who is a Member of Parliament, whose influence he hopes to use some day. Ezra, his son, is even more of a cynic, as the elder Girdlestone’s cynicism is mitigated by his supposed religiosity. However, he manifests a great acumen for business, sometimes, even surpassing his father’s sharpness in business matters. A series of disastrous speculations by the elder Girdlestone financially ruins the firm. After keeping the impending bankruptcy a secret from everyone for a time, he tells his son (whom he has fooled with a dummy ledger) about it, who is disgusted by his father’s rashness.(Excerpt from Wikipedia)
