silica on guinea pigs, and there are local complaints about vivisection for which Andrew has no licence. An official from the Society for Prevention of Cruelty to Animals comes and seizes the guinea pigs, and Andrew is brought before the local Committee under threat of dismissal. In his defence Andrew informs the committee that the blood they reported to have seen in his home laboratory was simply a chemical that he had spilt. He compares the continued use of white mice and canaries down the mine to his use of guinea pigs – both examples of sacrificing the lives of animals to save those of humans.

However, such is the financial greed of the medical profession, that it quickly becomes apparent that he cannot afford to buy any decent practice. After two months of searching in vain David Hope informs Andrew that a Dr. Foy has died and his practice in Paddington would be much cheaper because Dr. Foy, having been ill for a number of years, had allowed the practice to become run-down. The practice and attached house are in a poor state, and for many months Andrew has very few
