Mike is a school story by P. G. Wodehouse, first published on 15 September 1909 by Adam & Charles Black, London.

[1] The story first appeared in the magazine The Captain, in two separate parts that were collected together in the original version of the book; the first part, originally called Jackson Junior, was republished in 1953 under the title Mike at Wrykyn, while the second half, called The Lost Lambs in its serialised version, was released as Enter Psmith in 1935 and then as Mike and Psmith in 1953.

When Mike arrives at Wrykyn himself, his cricketing talent and love of adventure bring him success and trouble in equal measure.

Mike, due to poor academic reports, is withdrawn from Wrykyn by his father and sent to a smaller school called Sedleigh.

His sisters hope that he will get into the school team his first year, although his brother Bob and Saunders, the pro, are sceptical.

Mike is later allowed to play for the first after Wyatt is involved in a fight between some of the students and a gang from Wrykyn town, which ends up with a policeman being thrown into a pond.

The outbreak takes out one of the first-team players, giving Mike another chance; he plays reasonably in a poor game.

Neville-Smith, a bowler who has taken the other place in the team, plans a party at his house (he is a day boy) in celebration of his placement, and Wyatt sneaks out of school to attend.

On his way out he is spotted by a master, who reports it to Wain; the housemaster waits in Mike's room until Wyatt returns, and tells him he is to leave the school at once, to take a job in a bank.

The wicket is sticky from rain and Ripton notch up a good score, and taking the field reveal they having a strong bowler of googlies.

Bob gets out, but has given Mike time to settle in; with the tail of the team accompanying him, he deftly collars the bowling, finishing on 83 not out; Wrykyn wins.

Bored by their archaeology trips, they wander off one day, and Mike runs into an old cricketing friend, who offers him a place in a local village team.

Meanwhile, Stone and Robinson, not pleased with Adair's proposal to hold an early-morning cricket practice, decide they can safely skip it.

Downing tells the headmaster that he suspects Mike of painting Sammy, but it is found out that it had been done by Dunster, an old student.
