One Small Step is a 1990 novella written by British writer Reginald Hill featuring the detective characters Dalziel and Pascoe.

[1] In May 2010, Emile Lemarque, a French astronaut, is killed by a short circuit in his urine collection device at the moment he steps onto the surface of the Moon.

Retired Detective Superintendent Andy Dalziel and his former colleague Peter Pascoe, now the UK Commissioner in the Eurofed Department of Justice, fly to the Moon to investigate Lemarque's death as a murder.

Reviewing the American edition of Asking for the Moon in 1996, Publishers Weekly called One Small Step "an almost absurd swansong for the mismatched twosome".

[2] Reviewing Asking for the Moon for Booklist, Emily Melton called One Small Step "an intriguing but somewhat hokey piece of futuristic folderol".
