1475 Plea Rolls Translation

[sticksville]

I would be very grateful if someone could help with this Plea Rolls entry from the National Archives/AALT site.

It's the fifth entry from the top and concerns a debt owed by John Kytchynman of Keldholme in Yorkshire, capellanus (chaplain?, possibly of Keldholm Priory).
I thought I was doing quite well with early modern hands but this medieval script combined with Latin defeats me.

Ralph Gray presented himself through his attorney on the fourth day against John Kytchynman of Keldholme in the aforesaid county, chaplain, concerning a plea that he [John] should pay him [Ralph] one hundred shillings that he owes and unjustly retains etc. And he [John] did not come. And the sheriff was ordered to arrest him etc. And the sheriff now reports that he has not been found etc. Therefore, just as before, he should be arrested so that he is here within 15 days of Easter etc.

Thank you so much for this. My first experience of the help available on this forum and a good one.

The extent of the debt is interesting. According to the National Archives currency calculator, 20 shillings was the equivalent of £3456 in 1470. This was enough to buy 6 horses but only 3 horses in 1480 - horse inflation must have been quite a thing, perhaps a result of the Wars of the Roses?

On the above point, there are some interesting comments in this blog, though I don't know how authoritative they are …

When Henry came to the throne [1509], the quality of English horses was low. Although horses were very common, both for work and for the pleasure of the upperclass, foreign observers commented on the weakness of the native breeds. Before the War of the Roses (1455-1485), there was a state breeding program. The country needed warhorses, so they needed a source of them. On a network of estates belong to royal castles, each castle was required to keep a number of broodmares to be serviced by royal stallions. But after the thirty years of war, the stocks were devastated.
