Murder Against the Grain won the Crime Writers Association's Gold Dagger Award in 1967.

When a million-dollar bank robbery tips the new Soviet-American wheat treaty off-balance, Wall Street banker-detective John Putnam Thatcher steps in to even accounts with a thief dead set on Murder Against the Grain

John Putnam Thatcher, senior vice-president of the august Sloan Guaranty Trust, loathes crime, but crime has an ingenious way of seeking him out. This time he cannot by any means ignore it, for someone has had the effrontery to steal a million dollars from the Sloan itself.
And to make matters worse, the missing million was a Russian down payment for American wheat. According to far too many public officials, it is John Thatcher's patriotic duty to avert an international crisis, even if it means that the Sloan is rooked. In a matter of days he is dutifully embroiled with the Secretary of State, the Soviet Embassy, eccentric wheat farmers, striking longshoremen, and a team of pugnacious Russian astronauts, as he gamely attempts to recover the money and rescue the faltering Soviet-American wheat treaty.
Before Thatcher can get with the grain of the mystery, he has to answer some rather peculiar questions:
What was the Cuban Navy doing in New York harbor?
How did the American Potato Chip Institute become involved?
Why was the Leningrad Symphony practicing on a basketball court?
How on earth did a performing troupe of Russian ottrs that drink only vodka, dance the mazurka, and merrily assemble a three-stage rocket get into the picture?
And above all, who, from the dizzying cast of characters, has assigned himself the role of grim reaper?
