Det. Murdoch is surprised to be called into a meeting with Chief Constable Giles and the mayor of Toronto. They've received a film from someone apparently gassing his dog. The city has also received a demand for $100,000 - or the entire city will be gassed. Using some of the evidence found in the film, Murdoch is able to locate the site where the extortionist killed the dog and the police find evidence of a very powerful poison having been used. They think they've solved the problem when they find and dismantle a gas bomb but Murdoch determines that the extortionist likely has sufficient gas to create many such bombs. They decide to evacuate the city - and only then does Murdoch realize they have it all wrong. Written by garykmcd

Did You Know?


Julia mentions that the ransom note was written using "Baskerville font" which she said is very common. It is common but it is highly improbable that it would be ever used for a mechanical typewriter. Baskerville font is proportional (i.e., every character has different width) so it is not useful for the typewriter, especially the old mechanical one from the beginning of the twentieth century. Typewriter characters has to have the same width each, so non-proportional fonts (like famous Courier) are more likely to be used for them. See more »
