Reference excerpt

Sinister Errand is a 1945 spy thriller novel by the British writer Peter Cheyney. Cheyney known for his creations Lemmy Caution and Slim Callaghan, introduced a new character the half-American secret agent Michael Kells. It was followed by a sequel Ladies Won't Wait in 1951.

Synopsis Kells is on the trail of a group of Nazi spies operating in Britain to try and pinpoint the landing spots of V1 rockets to improve their accuracy. On his way he encounters several alluring but treacherous women.

Film adaptation In 1952 it was loosely adapted into the American film Diplomatic Courier directed by Henry Hathaway and starring Tyrone Power, Patricia Neal and Hildegard Knef. The story was updated and the setting shifted from wartime London to Trieste during the early stages of the Cold War.

Worked examples

Example 1 — a first encounter with Sinister Errand

Start with the simplest possible case. Write down what Sinister Errand claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sinister Errand before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sinister Errand ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sinister Errand

In research: Sinister Errand appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sinister Errand in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sinister Errand is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s World War II novel stubs, 1940s thriller novel stubs, 1945 British novels, so understanding it makes those chapters shorter.
In everyday life: Look for Sinister Errand outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
